Interesting thread...I do mostly woodworking, home construction/remodeling and metalworking, with some wrenching thrown in there.
I own a portable table saw, several routers and palm router, track saw, portable thickness planer are the main tools. At one time I had a contractor's table saw, jointer and dust collector, but those got sold because they take way too much space. I did keep my bandsaw, although I hardly use it. Also have a biscuit joiner and even a Domino jointer! I did honestly didn't think I would need anything else, until I recently bought a Makita power planer, and have realized how handy that thing is for trimwork and removing mill marks.
On the metalworking, I have a 210 Ironman, Miller AC buzzbox and a Lincoln Idealarc. A 4.5", 6" and 7" grinder and old Porter Cable portable band saw. A plasma cutter would be nice.
As far as mechanics' tools, I have a basic set of SAE/Metric shallow and deep sockets, a handful of ratchets/breaker bars and set of wrenches. No specialized tools such as press or anything like that, yet.
