Keep an eye on the bargain basment here (in fact you might want to check it now as there are some good sales on). Sometimes when stores like bestbuy, staples, office depot etc. run sales they are good online too. For instance best buy has sony 50 packs for 20$ good online or in store and if I understand right, its free shipping on them. The only thing I found online was 4x (you might want to check compusa as I think they might have it on sale too and it might be 8x).
sony 4x +r might be mcc 002 (mitsubishi) or ricohjpnr01. I havent used that specific mitsubishi media code but mitsubishi is suposed to be good media if you don't get ricohs. 4x -r might be MCC 01RG20, SONY04D1, TYG01. 8x +r is sony d11 or yuden000t02 and 8x -r is SONY08D1.
They are all good media manufactures. Ricohjpnr01 of course works great on my liteon (851s@832s). So does sony d11 and yuden000t02 didn't at first but after fighting with the firmware for a while, I found a firmware that burned them good.Anybody care to coment on any of these other media codes?
