It's not the price of the tk60, it's the computer part. I won't buy any board that I have to connect to a computer before I can use it. My hobby is RC Tanks, not rc computers. The tk22 and the IBU2 do everything I need them to do. Of course, almost all my tanks are airsoft and that makes a big difference.
Thank you very much for all the help guys, as usual, you have answered my questions and I now know what to do.
