Yeah, United Video in Wellington hire out PC games. I'll let you guess what happens to them.
if you're not too worried about 'service' then www.e-one.co.nz have stuff REALLY cheap, although limited product range. I can get you the VIP price too if you're keen.
Just had a quick look on Ascent.co.nz, and they have Plextor 40/16/10's on there for $420. Plextor are the fucking bomb, they make the best shit.
The other thing you want/need to keep an eye out for with any writer you buy is "buffer underrun protection". Ask the sales guys if it has it before you buy. This prevents you from making yourself a set of nice shiny coasters.
If you don't have a massively powerful PC, or you like to multitask while burning, this can be really worthwhile eh. If you don't get this, check the size of the internal CDW memory buffer. Bigger is better, but 2-4MB is pretty good.
Seriously, it may sound quite geeky, but it is a good idea to check those DAO+96 modes etc on that clonecd site above. (the link I gave above, and then "supported writers" on the menu)
A lot of new CDs are going to start coming out with some kind of copy protection, and having the "correct EFM encoding" setting could be valuable in the future.
Also, clonecd is the best proggy for CD to CD copying I am told.
