I have to agree with Deadeye. Cheapee bargains can be very expensive. I'm betting that the 20 minutes is closer to total life expectancy before utter frustration sets in and you stomp on it. Please forgive us/me for the negativity. It's just that we've all seen so many wide eyed people come out to our fields wondering why their Walmart, K-Mart, Radio Shack crap won't fly. This is not a cheap hobby but the costs can be controlled to an extent. Do check with a local club and try to get some help, they may have some used equipment for sale that is in good condition.

Good luck in your search.
