hmm, the price sounds about right...here's another kit which is for xenarc monitors...in theory it should work for any 7" monitors (99% sure on it), but just to make sure, i would call them up and ask...

the one you found will also work, but only on that size monitor (7")...just out of curiosity, what kind of monitor do you have?
