It is easy to understand your desire to buy "new" instead of "used". You stated you don't want to deal with having to search out a quality used saw, and worry about if you got the right saw at the right price in the right condition. Thus "new" makes it easy to just get started. However you mentioned a budget, and then you found the saw on CL, so the realization you might be able to get a decent saw, save money and use the money for more equip, is attractive after all.
Let me say, that any guy who has worked 8 years remodeling houses, has to solve a lot of problems to make things work, fit, look good, plus a very good knowledge of power tools, etc, in other words you have the right instincts and background to go buy "used", and make the right decision. Further you are way ahead of most of us who are white collar types and have taken up woodworking stuff as a hobby.
Back to the TS, ok your on a budget, but you don't want to buy something and have to replace it 2 years down the road. First sometimes that is unavoidable, not all our buying decisions will be good, and you might have to sell that item and upgrade. However it isn't hard to know which TS are worth buying. If you want to have an all around wood shop, you might want to consider a heavier TS like a hybrid or cabinet, which puts your purchase price for used in the $400-$700 range. There are a lot of contractor style saws that are very fine saws, in the under $400 range, and maybe that is the right place to start for you, but there are better hybrid or cabinet type you can find under $700 and you would use for decades.
One other point you said you have tried to get going on building woodworking stuff but it hasn't happened. You might be like the guy down the street from me, he is a cabinet maker, that's it! He won't do anything else with his tools & equipment. It's not fun for him, it is work. He is booked on cabinet orders, and the last thing he wants to do for relaxation is start up his table saw, and turn on another power tool. You might suffer from a little of this, you work with power tools, saws, etc all day, and while you might have the desire to put your practical knowledge to use in woodworking, the desire to get dirty and breath more sawdust just isn't easy after you did it all day. This might explain a little why buying "new" is more attractive even though you are on a tight budget. Buying "used" takes a certain amount of energy, and is a challenge, rather than face that hurtle (challenge), it's easier to go buy it new even if it may mean buying a budget model, and a Pro carpenter like yourself knows that quality tools & the right tool make the work go easier so, it grinds against you to step down in quality due to budget restraints.
All the above is a big guess, I don't have a clue, and if I'm wrong please ignore what I suggest.
If you are serious about woodworking, then acknowledge it is a hobby. Allow yourself time to enjoy it, this includes buying the right tools. Your money was hard earned and in your business you wouldn't buy junk just to get by, if you have to buy entry level until you have more money, buying "new" means you take the hit on depreciation so if you buy an entry level piece of equip, and want to upgrade you get stuck with losing 20-50%. If you buy a "used" item for the same price chances are you are buying something better than the "new" entry level, and if you want to upgrade you often can get your money (equity) back and maybe even a small profit (provided you bought the used item right), or for a tiny loss. Bang for Buck is usually greater buying "used", however you have to have the patience to wait for the right deal to show up and then move in and scoop it up. The last thing you want to do is go into debt buying equipment. Often buying new lends itself to debt, the buying juices are flowing and while you might have the cash for the entry level, for a couple of hundred more you can get the better model, so out comes the credit card, and you promise yourself to use the cash to pay off most of it. Unfortunately that cash usually doesn't quite get to the CC company at least not all of it.
If having the energy to go into the garage to do woodworking is difficult after a hard day at work, then budget your time the way you budget money. Plan your relaxation, and stick to it, you do that already with work, plan when to do the projects and how much time it will take. You know when the work load is light, and you might have energy to do something with wood at home.
Anyway, didn't mean to preach, just an old fart, who struggled and still does with the desire to get started...
What to buy first considering what you have..
