I'll add one more- not a pack for everyone- very (very) spartan, but also very light and very rugged (Dyeenma)- Golite Ion- 10 oz, 25 liters- if your a careful (and light) packer you can actually do 2-3 day trips w/ it
if your handy, or know someone handy- some mesh pockets and a little lashing can can make it a very capable pack- the price is right too at ~ $40
