you can get a nice one from ebay sometimes, and sometimes you can get one that needs more than 70 bucks worth of repairs making it so syou should have just bought a new one. It's hard to say one way or the other. Sometimes you win, sometimes you don't

about the cp+ vs the cp pro, the pro has the bell-hiller head and the plus has the hiller head. Also the plus doesn't have a control for channel 5 and the cp does for remote gyro gain or whatever else you want to use on it. Either way would work. To upgrade to the bell-hiller is 15 bucks from the hiller, and the difference in cost of the Tx's is 50 for the cp and cp+ and 55 for the co pro, but you're not that likely to sell that remote and get a cp pro remote for 5 bucks more. If you have your own computer remote then it wont even be an issue.
