My S14 for $2k, and my S13 last weekend for $600. Both in good exterior shape, suspension isn't very good on the S14, S13 has bad injector that's leaking horribly with what I'm assuming is carbon build-up in the cat, and the other has an injector starting to go bad and leak. Only trouble codes I've got from the S14 have to do with the fuel system (canister, evap cont, etc.) and a crank sensor, and I'm about to go check the codes on the S13 right now.
Oh yeah, the S14 is a 96 (150k miles when purchased) and the S13 is an 89 (149K as of saturday with it being parked in the driveway).
