Glad you brought this subject up! I was about to ask Asid the same question
Iam new to this too, and at first had no idea what was what or where to find simple info so I spent alot of time reading and surfing the net on my own. There is one thing that you sort of have to decide with Tx and that is which protocol you are going to use, unless you don´t mind having (spending money) more then one Tx.
It´s a bit of a commercial fight in some sence, and a matter of taste (preference) too.
The thing is that if you go for RTF (ready to fly) for example then you are tied to that protocol in some way. If you go with ARTF (almost ready to fly) then you can go for your choice of Tx/Rx. There is one protocol from JR Propo called DMSS if I recall which uses dual spectrum spread which will bind regardles of the Rx.
You also have Open source like Deviation.
Then theres the issue like warrantys. Big named brands will back you up, other brands may leave you in the cold. One of the reason why I went for Futaba.
Asid knows alot and Iam sure he will elaborate more, and I will also learn from him too
RCGroups is a wealthy source of information if you want to check them it out.
Here are a couple of list to guide you with which company´s bind to what...

He goes as far as running the Tx through a spectrum analyzer to show how good or not the protocol is working.
Care,
