There are three for sale locally. One is advertised at $150 and looks like it needs some TLC but reportedly works. The others appear to be in good shape and are advertised at $1000 or so. all appear to be cabinet-style saws and two of the three come with extension tables.
I've checked on Amazon and see some Unisaws advertised there at $2k and some at $1k but I don't see why there should be such a huge difference in price for what appear to be largely identical models.
