The thread about what's available would be a real help. I would print the kit and ARF(can't believe I just said that as I personally don't do ARFS) lists out and take them with you to the field and have the instructor pick one or two so you can get one ordered. I really like the fact that the guys HAVE NOT said to buy this brand or that of radio gear. Many threads have turned into arguments over which is better and why. Something you could do is check out what everyone else is using at the field, ask questions and see if they will let you hold some of them. A radio that doesn't feel "right" in your hands is not one you will be happy using over the long haul
