I usually dont' run with water as I don't run that long, lol..but during my recent training for a 1/2 marathon, i started requiring water. I, like you, didn't want one of those camelbak backpaks, but found their waist packs are great!

I got one similar to this one (below).

CAMELBAK WAISTPACK

It doesn't bounce around, it holds a great deal of water, and i can carry my keys, ID, and cell phone.
I've tried other waist packs, like with water bottles and what not, but the water sloshed around and bugged me. Not so with the camelbak waist pak....worth the money, imo
