I had a 10,000lb Challenger Lift installed in my shop last August and am very happy with it. I did a lot of reading on the net and talking to a local auto equipment supply company before buying it. I had orig wanted to go with a Bend Pack but the owner of the auto equip company talked me out of it (he sells both BP and Challenger). He explained a bunch of reasons why he believes the Challenger is a better lift, and says he has a lot more service calls on the Bend Packs as well. Price wise the BP and the Challenger were almost exactly the same. Both have all of the important certifications that a lift should have for safety reasons.
Regardless of the brand you choose, the best part is not having to lay on your back anymore!!!
