I know I want a Camelbak (or Platypus) hydration system. I just bought my Hardrock Comp, and a buddy of mine who also rides, mentioned these. Very cool!

Now......which brand??!! He has the 100oz. Camelbak M.U.L.E. ($79.99), and he really likes it. I noticed in the Bike Nashbar catalog (and their website), they also have the Platypus Thunderhead (on sale) for $39.50. Regular price is $79.99. Both of these can hold 100oz.

Decisions.....

And; the Camelbak and Platypus brands can be found on eBay.
