Yes, Toshibas are great drives.
I have a 1x drive (yes... I bought it around 3.5 years ago), and it is great. At that time, there was a lot of hype that DVD-ROMs would replace CD-ROMs within a year for software, so I decided to buy one. Big mistake.
Although my drive is great for playing movies (although I rarely use it these days since I have a real DVD player), it is very slow reading CDs (1st generation drives read CDs at 8x) and cannot read burned CDs (1st generation drives cannot read CD-Rs or CD-RWs).
None of these problems are around with today's DVD-ROM drives. They read CDs quickly and read burned CD-Rs perfectly.
I think you should probably not go with the fastest DVD drive around, but instead go with a reasonably priced drive. Until DVD-ROM software becomes more widespread, don't waste your money on the fastest drive; just get a good drive.
Hope my 2 cents helped!
