Well,

What do you want to do? Why are you upgrading? What features do you need, and what features do you think you may need in the future?

What is your price range? There are many good radios out there. What receivers do you already have? Are you making a 'clean break', or are you just looking for more features?

Knowing nothing about your situation, I would look into HiTec eclipse, JR XP9303 or Airtronics RD6000-8000 . There are many radios which will fill your needs.....uh...depending on your needs, that is.

HiTec Eclipse and JR XP9303 are both popular at my field, but some of the best flyers use older computerized radios which have been long surpassed by newer technology.
