I've been very pleased with the last 4 Toshiba's I've bought. I don't care for Dell but, I'm probably in the minority on that. I've just fixed too many of them.
For under 1,k each, I bought 2 Toshiba "Satellites". One is a home version and the other is a business version. The only real difference being size (smaller for biz) and O/S (Pro vs. Home XP).
I have no issue burning cd's on either of these cheap, unbalanced drives.

I have an external drive as well but, I don't remember what it's called and I wouldn't recommend it anyway. However, that's more for pc's that don't have a burner.
I'd recommend the Toshiba and no external drive initially and continue researching the best methods... After you get the best method, do a comparison to see if you can hear a difference. If you can, I'll do what you did!
