There are three tipes of LCDs that people on this board are mainly using:
1) The Lilliput, which if you're a lucky man, you could get one that work fine; also a cheaper solution...
2) the Xenarc, expensive but more reliable...
3) a new monitor from Linitx; you can find a very good review made by Confused, on his site,
www.mp3carisma.co.uk
As for the condensation or the rattling, don't worry; it works fine...
Another ideea would be to check the mp3car.com store...good prices too...
