This place:
http://www.tti-us.com/sim has some decent deals, and good support. I got a JR 631 radio, buddy box, USB Sim interface, and FMS with 700 planes and landscapes for like $139 or so. I think he also does Backyard sim for the same price? It's a good little store for learning newbies, and maybe instructors also. No G2 on there, but no big prices either. - Joe
