What you see are the complaints. When something is working correctly, people don't have anything to say.
Judging from the number of complaints, I'd say that the Lilliput quality is lower, because there are more complaints. Newer models are less prone to failure. There are also external factors that could lead to a unit failure such as shipping damage, user damage (especially in a custom fabricated situation where the unit has to be disassembled), etc.
So it's tough to judge. If you're going to purchase an LCD, I'd recommend using a reseller that's going to fully test and stand behind the product. That would include mp3car.com and DigitalWW int he US. There are other suppliers as well, but I mention those because of their obvious and overwhelming support of this hobby and community.
And for what it's worth, this is my 3,000th post. Yay?
