Oh. If you don't actually print labels, then the silver matte is perfect for you! You have the whole top surface to write on. No logos to obstruct your way. And it's not shiny and is not prone to fingerprinting. Actually the silver matte is a roughish finish--kinda like the white inkjet printable finish, only cheaper and not inkjet printable (I have a pack of the -R silver mattes, and they're nice).
Here you go!
NewEgg's a great retailer. Free shipping, very fast, very reliable. And because you're lucky enough to be in a state other than CA, it's also tax-free. I've done a dozen orders from them in the past.
And only $1/disc.
Or if you want cheaper, NewEgg's also selling G04 discs, silver matte. $44 for a pack of 50 (sale ends on Wednesday at 4 PST). And because you have a 812S, you could burn these at 8x too, with speedhacking (though I guess you might be safer sticking w/ the RICOHJPNR01 since they're proven to work well for you).
