RE: When making a purchase
Normally, I would prefer the local hobby shop to on-line mail order, however, when the economy went to the trash can a few years ago, we had two hobby shops, and both of them went belly-up. The closest hobby shop now is about an hour drive away.
I've always had good luck and success with the big houses - Horizon, Tower, and others. In fact, I ordered a set of servos from Tower a couple of years ago and got one servo and one glow engine for an RC car. I was billed for servos. I called them and told them about it. They sent me the servo along with pre-paid shipping to return it to them. They deducted the cost of the second servo as sort of an apology for messing up the shipment. That's pretty good service. I would imagine that Horizon would give the same level of service.
However, I really miss the local hobby shop. It was always a good place to just visit and shoot the breeze about RC. The shop owner was a classy builder.
