A while back in a forum discussion concerning OP machines Rick made the statement that the Challenger was "One Smooth Ride". I have found this statement to be true. I recently got my hands on one, but there is a story. I was messin around on eBay and saw a Challenger for $25.00, and of course had to look. This thing had been abused and finally hurled down a flight of stairs (I later learned). The description was honest. They said that it would not run and had a lot of detailed pictures. The shipping was to be $110.00. Did'nt like the sound of that, but then I noticed that it was in a town only 40 miles from me. I emailed them and ask if I could pick it up if I won so there would be no shipping. They said yes and to shorten the story, I won it for $26.99. Got it home and found out the motor was fried, counter-balance bearing shot and also it did not have a pad driver with it. I ordered a new motor, pad driver, counter-balance and bearing assembly, and a new rubber bumper. I disassembled the machine completely, re-painted it, polished the chrome, straightened a big dent, and replaced nuts and bolts. I ended up with a new Challenger for $500.00. Have been using it and it is as smooth as silk. I have another OP from another company that I like and have used it for about a year but the Challenger is smoother. Here are a few pictures.
