Hardcore stuff - DC game betas for sale!

Are you hardcore? Do you love collecting really, really weird, rare, and obscure gaming stuff? I know I do. But alas, I must leave for Japan soon, and I need to raise some cash. So, I'm looking to sell some Dreamcast betas I obtained a while back. All of these are official European beta discs, manufactured and authorized by Sega.

Quake 3 Arena
Chu Chu Rocket
Fighting Vipers 2
Metropolis Street Racer
Sega GT
Jet Set Radio
UEFA Dream Soccer (one of few DC games that was a Euro-only release)
Sonic Adventure Special E3 1999 version

All of these are just a stand-alone disc, white with blue text printed on them. Here's one of my not-for-sale betas to give you an idea of how they look:

NOTE: Yuji Naka signature not included.
My asking price is $35 per disc, save Sonic, which is $30. You're almost guaranteed not to run across these anywhere else... so if you want a cool little gaming collectible, consider picking a couple of these up.
