I've seen people use engine stands, but you'll have to get them higher off the ground to flip the car. Engine stands will be about 18-24" too short. The Auto Twirler and similar rotisseries are also made from heavier steel than a typical stand. I did all my work on a homemade dolly (made of 4x6 lumber!), then lifted the car on stands to about 40" to paint the underside. The dolly cost me about $80 to build.
