Congrats.... that one was on my list... but I really wanted to do some heavy custom programming... The MX is nice... but I ended up with the Pronto 9600. Yours is much easier to program.
The Pronto is really cool, and has a ton of options and upcoming features, but a lot more of a learning curve.
P.S. Learning Curve is a Euphemism for "BIG PAIN IN THE A$$"
Why do I always take on more then I can handle... hhehehhe
