Got my Darbee from Amazon via SolidSignal last night.
Won $100 Amazon GC from some conference.. so.. ended up paying like $160 for OB.
Looks brand new to me..I tested it a bit (10min) with Gladiator
Set the split Demo screen and when switching to HD-50 had a weird line artifact that was rolling left and right across whole screen, lol.. as if they needed an extra spear in there.
Shutting of Darbee for a second fixed that.
