The mp3car.com store is a very reliable &^ trustworthy place to do do business, I agree.
However, they are not the only reseller of small touchscreens.
There are people who will not venture into the forum for the mp3car.com store, for whatever reason. One of those people may be the person with the ideal screen for you. You wouldn't want to miss out on that potential opportunity by posting in the wrong place now, would you?
Trust me. I did this all for you.
Seriously, though. The mp3car.com store is not the only reseller of small LCD screens. Logic Supply, Digital Worldwide and other resellers carry a wide range of models from various manufacturers (mostly Lilliput & Xenarc).
