Chisels and Handplanes I sharpen, there's no way around that. I use a King combination water-stone and a strop, keeps 'em nice and shiny. I don't drill many holes, so I haven't worn out a drill bit yet. Or possibly I've been upgrading the quality of my bits faster than I wear them out.
I use cheap-enough sawblades (Freud Diablo) that it's not been worth getting them sharpened, and they last a year+ anyways. At least where I used to live the local sharpening service was expensive. Some day I'll upgrade to that Forrest II, but probably not this year.
I also sharpen my knives, but I use an old round combination stone for that.
I've never been apprehensive to use the Ridgid because it was lightweight. Even when just sitting on a surface, it's not easy to move around in normal sanding operation. Wanting a beefier machine is good, but I wouldn't let that be the only reason why you pass.
This is what I have, (pic grabbed from the web) an oscillating spindle sander from Sears, yes a craigslist find. It's a sweetheart. What I like best, it's portable and has a dust port and large surface to support stock. I store it under a bench. Never had an issue of it moving around. It does have provisions for fastening to a bench top. Just another option.
