Yep, I know decalgirl has the matte finish too (and great quality skins. I ordered one for my acer aspire one. Too bad I decided to sell the device in the meantime, but the skin was awesome, and it found a lucky new owner). But for international orders, Gelaskin is cheaper (3.50$ for international shipping, 9.60$ for decalgirl). So I thought I would just point out that there is also a cool 25% discount there
I don't know about gelaskin quality, though.
