I'm also flying one and having zero issues with it. Thinking of converting to Weatronic but not quite ready to spend more money on them unless they adress their customer service.
So flying HOTT now and very happy with it. Telemetry features are very similar to Weatronic, and the top display for realtime telemetry offcourse.
Programming is very easy and straightforward, as all Graupner TX's. Bigger and heavier than a MC-24, but a very solid feel because of the magnesium body. There were some issues with the side sliders but are adressed, stronger material is used for new TX's and upgrade parts are available.

On the German RCNetwork forum there is talk of a MX-32 (hand held type) TX beeing in the works, but don't get your hopes up, the original release date for the MC-32 was beginning of 2009, I got mine FEB2012.
