People mostly use Spektrum gear, you can get cheap Rxs is abundance on eBay (called Orange Rxs). But a basic controller (A DX5E) is more than your link.

Your other options are:
The Planet 5 set (popular with beginners) I've never used them.

The Radio Link set. Cheap but we had endless problems with them binding and actually binned it in the end!

The FlySky set, another cheap option, never personally used though.

And the HobbyKing super cheap set, which is actually a re-branded FlySky set. I have one of these and was very impressed. The Aussies use them a lot.

And you can re-program them, which I detail here:

The set you linked should be fine, but I'd stick with stuff other people use for the mean time since they can then help you.
