I have no sympathy for the guy. I checked regularly for a period of nearly two years for those random, very brief moments of availability to buy GDEMU and was never around to buy it. Ditto for Rhea. Ended up just waiting for reasonably priced ebay units (relative to some of the insanely priced listings) and snatched them up last year. I justified swallowing the markup because I was fed up with dude’s incompetence at providing his own product to people ready and willing to pay. What sucks is that it’s only gotten worse price-wise for anyone who wants to go that desperate route, further showing this guy is fucking up and refusing to meet the considerable demand. If the clone works well, I say set aside any guilt and just go for it.
The Everdrive situation is the total opposite and should be supported. Good customer service from Krikzz and readily available from his site, his Amazon page and official resellers like Stone Age.
