Good second transmitter

[Rocking Donkey]

I currently have a JR X-756 stick transmitter which I have swapped the module to Spektrum. I would like to get a second Tx and was wondering what people use and what they think of them. At my club everyone seems to have a KO Esprit, Futaba 3VC or Sanwa Gemini.

On eBay the value seems to be with Tx's with 5 or more channels for Air based models. Does anyone use one of these and is it easy to limit the sticks to one direction?

I would like something with adjustable end points and preferably a few model memory and Spektrum compatible. All ideas and opinions welcome
