The radios previously mentioned are all great radios! The technology is very similar between them all. Some have features others dont. Once you have an idea on how much money you want to spend then go to the LHS and physically hold the radios. Find the radio that is most comfortable for YOU. I personally use a DX3R. I found for me it was the most comfortable and has the functions I need for both electric and nitro. To me comfort is a must. Holding an uncomfortable radio for a 30+ minute main will really affect your driving...
