The 2 brands are Lilliput and Xenarc. That's right, 2 brands. Small VGA screens are neither common, nor are they in high demand with respect to all the composite quality screens for other HU's. So there are 2 companies that see the market and take advantage of it by selling us their stuff at outrageous prices. But hey, what are we to do?
All the brands on eBay (I should say most, to all) are all re-branded lilliput models. Same screen, same controller, same everything but the casing has a different name and logo.
All motorized units will fail. Not if they fail, but when they fail you will have one hell of a bad day. You wont be able to get your screen out, and you will be out of $400.
The non-motorized kind aren't as cool, and the only advantage over mold-ins is the space saving design.
So, why are you going flipout?
And incase I haven't made my point, here it is bluntly: There is no good solution.
