Just wanted to share my experience, and say that I have had Excellent service with maXYZmodules. I myself, a long time ago fried my second module when I first got it, maXYZmodules fixed it for a small repair fee, (after I told him what I did), he repaired it, and had it back to me in days! I just recently upgraded my old module from TTL, to analogue, and once again excellent service! Thanks !!!!!
