There's always the option of cinder blocks and plywood

Not attractive, but cheap. I built this one:

But it's for a 75 gal. (You could ajust it to make it smaller, or just search for a diy 30 gal stand.)
Other than that, as stray and Spots mama said, craigslist or a sturdy coffee table. 30G is ~250 lbs (full), so if you and a friend or two can sit on it, then it'll be alright for the tank.
