between me and my father we have just about every tool known to man (mostly he has them :P)
he has this old table saw that's about 27 years old and it still works like a champ... when he's using it He's been using it for so long that anything that's wrong with it he automatically compensates for, and he can use it to cut just about anything there is to cut.
A mashed up jigsaw is a bit more difficult though i suppose
circular saws are nice to have too! and these days you can get a crappy table saw that is really a table with a circular saw bolted underneath it.
