I wanted to buy this over the winter and no one had them. I am still temped even though I now have 3 rotisserie setups (Kettle, Genesis 5, and Broilmaster). Should work on either gas or charcoal version. Comes with battery powered motor and should be swappable with all other motors. If I did not just buy a battery operated motor I would be more tempted.
