I'm with Mack. There's little you can do with a table saw that you can't do with a circular saw, and for your projects, I don't really see where it would help (unless you're going to do fancy joint mortising and stuff like that). I'd go with the miter saw... and make sure it's got enough height to support more than you'd ever want to run through it, and a simple but sturdy mechanism for holding things in place while you cut. I regret that little aspect on the inexpensive jobbie that I picked up...
Some of the local hardware stores around here will let you rent tools instead of buying them. It's a good option if you're only going to need it once, but I've found that by the inevitable second rental, I could have bought one....
