Need a Recommendation on a car Rotisserie

thank you a lot of good input.... i like the acme threaded adjusters for height balance. i'll be on concrete in shop so good there. i just don't want to be under a weak one, i 've seen some bend and looked a little scary. My friend owns a metal fab shop, i may take ideas from the accessible systems style 3000lb rotisserie and put some extras that may work better.
if i go that route ill start a thread step by step. stay tuned... thanks for input though
