If you are not looking into high-bright lcd, datalux would be a good solution for you. Im not saying that you ShoulD buy it, but research more to find out the specifications of it.
The one on eBay is a better model than i used to have (screen was 150nits, really bad with the direct sunlight).
http://www.datalux.com/monitors/lmv10.asp claim to be a 500nits?? (before or after touch screen layer was assembled??), resolution? (640x480??)
Its up to you which will you buy...use search...many ppl here had experience with Datalux lcds, you can ask them. And remember this one is already with controller and touchscreen ready to use.
