You should be able to get a decent (new) unit for that price. You probably won't get aluminum frame, or maybe not smooth sides, though. I looked at the Wildwood line, made by Forest River (forestriverinc.com). My dealer came up with a price of 18. 5 for the 32BHSS 5th wheel. I liked the floor plan, but decided to step-up to the Sandpiper, which offers bedroom slides, aluminum frames, & gelcoat sides. Did cost quite a bit more, though.
A friend of mine is getting a Cougar by Keystone (keystonerv.com). It seems like a decent unit (aluminum frame & smooth side), and is priced in your range.
My last unit was wood frame (bought "cheap", to decide how we would like/use it). I had no problems, and sold it before the warranty ran-out. If you're looking to test the waters, then this is a good route to go.
As a rule of thumb, you shoud easily be able to get 10-15% off the first number they throw at you. If you start working different dealerships, you may do even better.
