RE: Building my first kit
You'll have someone right next to you though. It should still be fine. Some people think training that way is better anyhow (I prefer the buddybox).
Somebody correct me if I'm wrong, but I think you can still use the buddy box system on 2.4 ghz. (Unless it is a cord from a 72mhz to 2.4ghz. I don't know if that is an issue.)

Edit-
Still go with the retracts. [sm=thumbup.gif]
