Vice advice is right on - posting an ad for a good ole vice for a community bike shop could get one donated. Lots of folks with unused shops out there.
The other thing to try on a seatpost is to take the bottom bracket out, put the frame in a stand and flip it upside down, then drip some penetrating oil in the seat tube. This takes some time, but worth trying before in there with a hacksaw or risking damaging a sweet frame by pounding & wrenching.

a vise is good for stuck seat posts. flip over the bike, insert seat post

Yeah, we have a 4" vise and it has come in very handy for things like this. It of course also needs to be bolted to a strong, sturdy table.
any other 'stuck seat post' tips?
