GSA-4120B is cheaper than Plextor PX-708A though a bit more expensive than NEC ND-2500A, with some differences in specifications.
Taiyo Yuden 8x DVD+R media now cost about US$1.5 per disc in Seoul. One of the other media known to burn at 12x speed with GSA-4120B and PX-712A is Ritek/Ricoh JPNR02 type. Ritek seems to produce them and they are sold under some names, like Lite-On, Platinum, RiData, and so on. Here in South Korea, RiData 8x DVD+R is just 10% cheaper than TY 8x DVD+R. I like TY’s spindle case and upper disc design more than those in Ridata and I trust TY more, too.
For now, this seems to be the best combination to me. Until DVD+R DL media price comes down to something like US$2 per disc, that is.
For the consumers in the US, keep in mind that recordable DVD prices in South Korea usually are 50% higher than those in the US, for both drives and media.
I’ve been eye-shopping for camera/camcorder. Hitachi’s 380 DVD-R/DVD-RAM camcorder and Sanyo’s C1 SD-based digital camera that saves 640x480 30fps video to MPEG-4 files seem the most practical.
580 model seems much better but not available here.
