Just found this at my bookmarked hot deals forum.
Verbatim 2.4X DVD+R DL + jewel case - $5.50 to $5.80 ea
Should be worth a shot to order one and try. But these won't ship to you in probably another 2 weeks from what I hear.
And hot for me because I'm still waiting for 100% confirmation whether these mods will work because I would hate to buy a sony dru700a or genuine ltr-832s.
This was posted several days ago. Many people (including me) are quite skeptical. The price is waaaaaaay too low (too good to be true), and the dealer has a miserable reseller rating, with people who claim to have been ripped off by them.
