With the upcoming frame project and a few others, I decided to invest in some fixturing tools. Hopefully I can buy a table before long, but even after I do, I'm wondering y'alls preference, magnets or clamps?

I've found magnets can mess with the arc a little, but aside from that, do you prefer using magnets to fix angles or corner clamps, vise-grips, etc. and why?

Right tool for the right job, and I'm sure certain things call for one or the other, I'm meaning in general. Not a lot of room in my budget (if you can call what's under the couch cushions a budget) so I figure I'd get some input before buying a bunch of stuff this weekend.
