well, from my experience:
1) touchscreen is crap. went out within days of purchase. very common, and no fixes except to replace with a better quality unit. Digitalww has them.
2) Jurassic park or similar image when cannot sync. Not much of a problem anymore, but frustrating knowing that you bought a USED pachinko machine LCD as a NEW monitor.
3) Connector (din plug) is CRAP and is now upgraded. Chances are you will get a new version, but if not, it needs to be cut off and thrown in the nearest river. Causes all kinds of problems with the color.
4) Power supply "Egg" known to cause problems, not reliable, poor design. Most people just power it from their power supply or a dc regulator circuit.
5)IF you disassemble the unit, the ribbons do not fit correctly. They are 1 full pin short of being correct, so if you center them, it wont work. If you position to one side, it wont work. Then, you try the other side and its fine. Very frustrating until you figure out what goes where. easy fix, write it down! I think Digitalww has the correct ones as well.
Why not look at buying a GOOD monitor from here? I am sure he can work out shipping. There are quite a few people happy with their Lilliputs...but very few unhappy with their Xenarc!
Minus the shipping, its about $495 AUD ($379 usd)
