If you're willing to think outside the box, keep your eyes peeled for creative solutions, you might get something awesome. My son bought a solid wood door from a 2nd hand remodeling store (kind of like a Habitat for Humanity ReStore). He put one end on a 2-drawer filing cabinet, the other end on an iron base from a back yard patio set. The whole setup is solid and firm, and I think he paid $25 for all of it.
