Agree, overall "YUDEN000 T02" is my favorite and best performing media, bar none. You'll pay a bit more, but you can often find sales and free shipping.
TY -R performs excellently too.
Beware substitutes, but for starters you can try: Rima, Supermediastore, Meritline...not sure if Newegg and Mirocenter still carry TY +R.
Like I said, be certain to check the MID....sometimes you'll have to guesstimate based on user reviews. Your choice on that one.
Take a look at cdf's Bargain Basement thread.
BTW, no such thing as TY +R DL media...and TY -R DL was a bust.
