Those are gonna come shrink wrapped in packs of fifty. Hope you have a couple of empty spindles laying around. It's UPS ground, so you can expect it to take a week or so, depending on where you live. I'm all the way across the country from City of Industry where meritline is, so it's usually a full week for me.
I do hope you have updated the firmware on your 104, from the original, so as not to have the potential fire problem. BTW, you can get a 105 or a 106 for about 130 bucks now, even less if you dig around, so it might be more economical to move up there. 8X media is probably gonna be megabux, which means the 4X will go even lower. Even at 4X those hundred discs you ordered, you would save 25 HOURS of burning time at 4X. I've been staying behind the curve a little because then I know the drives are cheap, have all the bugs worked out, and the media is, well, deals like this one. To me 15 minutes down to 8 minutes isn't nearly as attractive as the move form 30 minutes to 15 was. Especially if the media is 3 bux a shot. Just my thoughts, though.
Anyway, thanks again.
