I said not a lot of choices, you can get a 1:1-1:3 and that's about it, throw in a HDD model which will probably be 1:1 that's not a lot of choices, I wasn't saying brand wise, just the fact you'll have about 3 different configurations to choose from.
the one I linked to cost a bit more, but Microboard makes outstanding duplicators with far better optical drives than most of the cheaper ones, which usually have Lite-On drives. Nothing against Lite-On's but they have no business being in a dupper that will possibly be used to make 100+ discs a day. If somebody's going to buy a unit that has 3 or 4 drives in it, they should budget maybe 100$ more and get a unit that has NEC or Plextor drives and skip the Lite-On's which won't hold up. That's just my opinion though
