I would not want to work in the garage. Even in a more mild climate than I live in, I wouldn't want to expose my dies and electronics to humidity.
I started on the Stack-On reloading bench:

Aside from very limited storage, it was actually quite good. The next addition was a home project with Pops--nothing fancy, just leftover lumber and some heavy planks from the old lake house for a benchtop. Again, worked fine, once I figured out how to get the the two-piece benchtop solidly fixed.
For the monster expansion, I went with a pricier bench from Home Depot:

It's perfectly solid, although I placed plywood to back the underside of the top where the press mounts are bolted (Ultramounts for both the Co-Ax and the 750). It will wobble side-to-side, but not front to back, although admittedly I haven't really gone in and made sure everything was tightened on it. Not to mention, it's free-standing, and still on some cardboard to make it easier to tweak the location.
There are a lot of bench options that work. Lee makes a stand for their presses, but there's no workspace. And you need workspace. I'll be up to 20', and I think I'll just about have enough, although I'm planning on having everything out and ready to use. Frankford Arsenal makes a little table, but I've heard it's a wobbly little thing.
Hence why I say, get to work on the bench now. Buy a leg kit and a top, build your own, whatever. Take your time, spread out purchases to get nicer stuff. Even if you discard the idea of reloading before you're done, it's awful nice to have a big, wide open space to work on your guns.
And yeah--no TV. I know a couple accidents caused by that. I'll play music, but I don't jerk around skipping songs while I reload.
