Well, to guarantee it's functioning (prior to shipment) I CAN take a short video of me playing with it. Now, in the past I've been able to overinsure items that I've shipped out, that way if there's any damage during shipment, it's a gurantee to be fixed.
I've done plenty of business here on HybridZ my membership here has always been upstanding. Hell, I gave Doc the idea for his avatar I've been around a little while, and I'm not going anywhere anytime soon. I too have been screwed by a member or two (to the tune of about 4,000 on one deal), it sucks, I know. I've also got nothing but good feedback on Ebay (same user name as here), so take it for what it's worth.
