They're [mostly] arcade monitors of various descriptions, from CGA to VGA, etc. which means, yes, they can be used for mame(assuming you know how to do it), and according to many many people who have bought them, yes, they are good.
In addition, as you should notice from this post(and the others floating around), that Rick is a stand-up guy, and it's my personal opinion that he would never, ever sell you(or anyone else) junk. In my case, he even went waaaaay out of his way to help me fix a monitor that I did not even get from him! How awesome is that??? Pretty damn awesome indeed!
As for pricing, see what he has on the site that is appropriate for your needs and email him for a quote. You will find his prices quite reasonable. Does that sorta answer your questions?
