I am too lazy to look, but someone here posted a homebuilt one out of Harbor Freight engine lifts. Looked really nice and would be pretty cheap to make.
the home built job works well as well! measure betweem the rearbumper mounts for the rear hook point. measure the front frame mounts for the front. then you just attach those peices to the engine stands round neck with a welder and vuala! instant rotisserie.

due to budget cutbacks, the light at the end of the tunnel has been disconnected for non payment.
