Hi Ne0SiS, welcome to our forum!
Nowadays, about everybody buys multiformat writers (writers that can do DVD+R(W), DVD-R(W) and some even DVD-RAM). 4x Is the regular speed for the moment.
The most popular writers are the Sony's (51x-series), NEC (1300a), Pioneer (A06) and the Optorite (DD0203). They are all pretty good drives (if it were up to me, I'd pick the NEC or the Pioneer) and plenty of information on them can be found on our forums.
I'd think you'd best do a search for the drives I mentioned. Using our search button, you will find lots of threas with quite detailled information.
If you don't find what your looking for, feel free to ask
