radio gear suggestions/help

[git-r]

Hi all,

wondering what you guys would suggest as a pretty decent wheel transmitter/receiver combo for an xray t3?

I have two t3's and have seen some combos advertised with a second receiver included so was thinking along those lines..

Budget wise around 100 and very happy to buy second hand.

im very new to all this and am probably getting confused, but do some of the more advanced transmitters display live voltage/temp and lap times?

thanks in advance

Sam
