RE: do a search
Oops, I missed the post about you already having bought one. Obviously, if you are in the market for a transmitter then you might as well get the most updated technology, I would definitely have done the same thing! My argument was that I didn't see a need to upgrade to one if you didn't really need a Tx.
Congrats on the new purchase, I have a regular DX7 and love it. I am sure you'll enjoy yours as well.
