Not a bad idea with the thin-film-anti-glare-oleophobic screen protectors, don't have to wear our gloves anymore?
Sounds like an ideal protector, I looked up the 22HD size:http://www.ebay.com/itm/111368737674
I'd have to shell out $60 to fit my 21.5" panel.
I have to assume there's some difference from this similar $26 film:www.ebay.com/itm/271313758276
$60 is not a shocking price for the size, but personally in my ongoing build, I'm budgeting cheaper and making possible sacrifices of frictionless feel and finger smudges for something less expensive.
Heck, I'm strongly considering just drawing on a bare LCD panel, no additional glass, no acrylic, and no film... but that's another post.
I can only say I've had a real Cintiq in front of me twice. So I don't know what's Cintiq® "right feel". But hey, whatever feels good to you is what's right. Glass is hard with high static friction, acrylic and film coating have some give and low friction. Either way you're always drawing with a plastic pen nib, so the feel is not going to vary all that drastically...
FWIW, consider wearing a drawing glove ontop glass, it really helps your palm not stick.
