I will put in my vote for the MX-3X also. More than enough features and Ive smoked guys using $400 radios... Just as fast as the more pricey (and bulky) M11 series.

In fact im about to buy another MX-3X since it makes more sense than buying a receiver alone. That way Ill have a back up radio as well for the slight extra cost.

Also too many issues going around with the spektrums and their "cheap-e-ness". It will be a long time and they will have to revolutionize TX's to get me to even think about one.
