I can share my recent experience. I have a very old router that I wanted to replace. The things I did not like about the old router were:
* Despite its size, it could use only 1/4 inch shank bits. There was no way to fix that.
* It was underpowered for its size.
* It was large and top heavy, which made it difficult to control.
About a year ago, I turned to expert friends to help me choose what I needed. On their recommendations, I bought a compact router kit and a mid-size router kit. "Kits" come with both plunge and fixed bases. You move the motor between the two bases. Here are the models I bought:
* Makita RT0701CX7
* Porter-Cable 895PK
I have used both routers and both bases a lot since then. Overall, I am pleased with what I have, but I did learn a few lessons along the way.
Compact routers take only 1/4 inch shank router bits, which is understandable, considering their size and power. It is why I wanted a mid-size router set, too.
Since you plan to use the router in a router table, you may want to consider mid-size routers that have a built-in lift feature, where you can insert a crank handle through a hole in the router table to adjust bit height from above. I learned a few lessons about that.
You effectively give up the fixed base to the router table. If you want to do handheld edge trimming with your mid-size router, then you can:
* Install and remove the fixed base to and from the router table as needed. Trust me, that gets old very quick.
* Buy a true router lift and keep the fixed base for edge trimming.
* Use the router table instead of handheld edge trimming. That may not be practical if the piece is very large, like a shelf I was working on.
* Use the plunge base for edge trimming. I tried that, but did not like it, and I missed the fine-tune adjustment knob that is built-in to the fixed base.
* Get another fixed base. Porter-Cable was not selling it separately any longer for my router.
* Use a different router (like the compact router) to do the edge trimming, if you have one and the bit will fit in it.
* Get a second mid-size router with a fixed base. That's what I did. I bought a matching mid-size router with the same fixed base (no plunge base). Now I have a spare motor and two fixed bases - one for the router table and one for edge trimming and other uses. Yes, I considered buying a lift instead, but this seems like a better fit for my needs.
The fixed base on the Porter-Cable router is calibrated in standard units only. I would have liked dual standard/metric indicators.
The lift feature on the Porter-Cable mid-size fixed base also supports a second hole to lock and unlock the height adjustment. Other mid-size routers support only one hole for height adjustment, which means that you must reach under the table to lock and unlock it when you make height changes.
Rockler makes offset router collet wrenches for Porter-Cable, Bosch, and DeWalt mid-size routers. They make it so convenient to change router bits from above the router table. I have had them for a while (paid full price!) and highly recommend them. They are exclusive to Rockler
-> Note: They are on sale right now (through 1 October 2020) for 25% off.
Not all accessories mentioned in the user manuals are available to buy:
* The dust collection handle for the Porter-Cable mid-size router fixed base is no longer available.
* The supplied edge guide that comes with the Makita compact router fits only the fixed base. The adapter to use it with the plunge base is not supplied and not available for purchase. That makes little sense to me. (Note: You can buy a different straight guide accessory to use with the plunge base, but then what is the real purpose of the supplied edge guide?)
The Bosch mid-size routers require a special adapter for guide bushings. You can use Bosch-made guide bushings with it. If you want to use the common 1-1/4 inch guide bushings that you see everywhere, then you need a second Bosch adapter to adapt them to fit in the first Bosch adapter. Yeah, really. That's okay - they don't cost much and the quick release is convenient.
The Makita compact router is very nice, but if you remove the plastic base, watch out for the sharp edges on the metal base frame. Other router base frames may or may not have similar issues. It is how they are made.
I hope this helps.
