Someone was recently debating getting hardcoat Verbatim media or getting normal TY media as a backup medium; the vote was cast in favor of getting the TY, assuming the extra protection was not necessary. I think a discussion also took place regarding gold/golden media, and the general consensus there was that the gold layer, if there is a genuine gold layer, would not necessarily be better than a well-written TY disc for archival purposes.
That particular drive is probably a bit overpriced as there is a high demand for it. Assuming it is the proper AD-5280S CB-PLUS, it is one of the only drives known to overburn DVD+R DL media, and is highly sought out by...the XBox 360 community, I believe, to avoid having to truncate images of their game backups. May also be highly sought out by the rest of the DVD backup community for the same reason. Also, it is typically used in duplicators, so the tray comes out a little bit more than normal drives...any little extra feature commands a premium price, it seems.
