I just joined the team. I've been running both my Microtracker and MT II and the MT II is now making flat line wavs. Thought about getting a 722, but I want to keep using my V3 and this has the s/pdif and mini usb connections I am used to. Got a couple of 16 gig cards (SanDisk Ultra 16 GB Class 4 SDHC Flash Memory Card) that Amazon had suggested.
