Welcome to the forum. Like Daren said, no question is stupid, except the one you don't ask. Always good to see new turners.
As far as which jig is the best for sharpening your chisels etc, it's a matter of choice or preference, but some advice from an older turner always eases your decision which to use. Here are my thoughts on the various grinding systems you mentioned. The Tormek is a great system but expensive, I used mine for years. Does a good job but is slow. The Sorby is supposed to be good but I never used one. The Wolverine grinder and the Verigrind jig is a great way to sharpen your tools and the cost is reasonable. If money is a problem for you there is a turner named Darrell Feltmate that has a website where he explains how to make your own and it is simple to do. I already bought my wolverine before I saw his site explaining how to make your own jigs.Even if you don't want to make your own his site is teriffic for learning all kinds of things about turning, if your a new turner or old.
Once again, welcome, and we look forward to eventually seeing you post pictures of your turnings. If your interested, check out my turnings under Mitch Gallery. Good luck and keep them turning. Mitch
