Amazon has the Velocity DVD+R 8X 100-pack spindle for $29.99. Whether they will do right by you is dependent on your DVD burner. Make sure you read the ratings/comments to see if these are suitable for you.
How do the Fuji disks compare to Ritek (Ridata) media? I've been using their 4X DVD-Rs, along with Apple branded DVD-Rs and have had a coaster free existence.
I actually experienced some issues with the Ritek's a while back (2x +R's), but have had ZERO problems with the Fuji +R's (8x). No coasters whatsoever.
I just picked up a 100 spindle of Taiyo Yuden 4X -Rs from supermediastore.com for $35.99. Free shipping. They are one of the few discs that my finicky Liteon 4x drive, and the players in my house, all like.
Read the reviews on those discs on that site, and most eveyrone is complaining about them. Some people get consistent coasters, but even the people with luck are getting an unacceptibly high amount of coasters.
My rule of thumb is to stay away from generic media, especially when dealing with DVDs.
Be careful with those huge spindles. You don't want to get stuck with 100 crappy discs. Sales are usually on 3rd or 4th class media. Heck, I used to think that Memorex made a good product until got some of their DVD+Rs. Not really the stuff I want to preserve my family memories on.
