Hi Tippy I the Turnigy 9x Tx but the new 9xr is a good relatively cheap choice.
Both are good beginers txs but you will need to buy a module such as the Flysky
if you are going with the 9xr route.
There are two great threads on here for both Tx radios.
I also have the 450 CCPM which is almost complete just haveing a few teething problems
a great little 450 with the aluminium head not the cheapo plastic one not so good.
Easy to build and with the ammount of help by the guys on here you cannot fail to complete it.
Just thought I would let you know buddy
Get a good Gyro though I got the GP 780 Align gyro with the ds 520 digital tail servo but others will come along and tell you of others
like the Spartan Quark which is a blinder bit more expesive though
