Cinemartin Releases a 7” HD Monitor for 99$ Bucks! I’ve purchased cheap monitors before and to be honest I think I got out of them what I needed from them at the time I could afford them. With technology performance and functions increase and price usually decreases.
This might be a great option and for $99 bucks you just might get out of it more than it costs!
