+1 for trolling craigslist.
I've seen amazing deals on cabinet saws. You just have to check 2x each day and be first to email. Especially look for the cryptic "Table saw, $500" posts. You know, the ones that don't mention the manufacturer, only that it's a 3-phase, 5hp motor. That's how I got my Powermatic. The fence was missing a part, and it took me a month and several posts here to find it, but I ended up with an inexpensive PM66.
If you buy a portable, you'll wish you had the cabinet saw until you bite the bullet and get a Sawstop, Unisaw or what-have-you. Better to figure out what saw it is you REALLY want, and then look for deals.
(But some saws *never* come up on CL -- Sawstop, for instance.)
