I have a table saw, skillsaw, router, jigsaw, dremel... now that I think about it, I have quite a few tools, mostly inherited from family members who did not need them as much as they thought they would. I have my brother in law's band saw, for example. Nice. Not necessary. For bicycle-related things, I have never used the table saw or skillsaw, and have used the router and jigsaw for only one project (so far). The dremel, however, has been useful for many bicycle projects. Bench grinder and bench vise have proved very useful.

Kinda wish I had a drill press, though!
