I suggest getting the Plexwritor. I have a plexwriter and I have had no touble with it whatsoever. I know many people that use them as well. Truthfully, I really do not know anything about the TDK writer. I know that the plextor has a lot of advanced features like burnproof. If you want to find the lowest price for that burner check out
www.pricewatch.com. I buy all of my comptuer hardware from vendors off of here.
