I'll tell you though it's disadvatages first, and then go through the advantages:
the disadvanteges are two and only two:
1) It takes a long time to recognize an inserted disc.
2) It is really slow for DVD ripping (even with riplock disabled).
On the other hand, 1)it has very good burning quality (never wrote a disc that wasn't readable -or even hard to read- by any other drives/decks I've tested)
2) It burns really damn fast with practically no quality loss
3) it is the most firmware supported DVDRW device
Personally, I tried Liggy's IU5 and IU6 firmware, but ended up using Mad Dog's modified firmware (much cooler, with riplock disable option, RPC1 and manual bitsetting)
Overall, i think it is the best you can buy, and definatelly worth it's money.
