I think the Sharp is dual scan - so you probably don't want to use it (dim screen, limited viewing angle and poor refresh speeds.)
I believe the other two are tft and I imagine they should work with the Flat-panel.com controller. Best to send them an email to be sure.
I've looked pretty extensively for "cheap" controllers as I suppose many others here have.
Unless someone has seen something that I haven't ~$200 is about as low as they get .
