Give it 5 years and we'll find out how unreliable they really are. Like I said, I've had my Numarks for 3 years and have yet to have a problem. Like magpie0001 said, they haven't been around long enough, wait till people are using them for 8-10 years and then we'll see. Until then I'm going to go play some of my records backward at 78RPMs at a +20 pitch, any 1200 users care to join me
