Toshiba, Pioneer, Liteon, are the big names in DVD drives. Apart from those, Asus and Aopen make some nice DVD drives too.
Almost all the DVD drives are priced competitively. The Toshiba can be found at newegg for $39 I think. They're fairly fast and not too loud. The others tend to be in that price range. Pioneer has slot and tray load models. They're not too noisy either. the Liteon is probably the fastest DVD drive out there I think, but it's one of the louder ones in my opnion.
Liteon, Plextor, Teac, and Yamaha are probably the most popular brands out there for CD-R/RW drives.
I think you'd be fine going with an older CD-R/RW drive, but the price different can be minimal for some brands, so look closely, the difference between an older burner and the newest burner might only be $10-15 in some cases.
So while I'm not advising against it, I'd say that you should keep a close watch on the price differences, you can always burn at a slower speed with a faster drive. It'd probably be convenient too since you wouldn't have to think twice about whether your media is holding up at those higher burn speeds and when the time comes that the media is readily available and you want faster speeds, it'll be there for you.
