Radio Question

[Sower]

Hey guys - right now I'm running a Spektrum DX3.0 and I'm thinking of getting a better radio for next season. I want something that's really fast and won't glitch. I guess it would also be nice if I could have a lap timer on it too. I don't know a whole lot about radios, so I'm not sure what else to ask. If any of you have a link to a site that has compared or reviewed some of the radios out there - that would be awesome too.

Any ideas? Thanks guys!
