I am currently using this at the moment and so far so good.

I plan to upgrade this at some point, but for now it does the job. The basic features are :
2.4ghz
20 model memory
LCD display
Digital trim
It is not a high end model, but it works fine for both my cars and to be honest at this stage if I had many more settings I wouldnt know what the hell to do with them anyway!
And it is £74.99 brand new off the shelf!
