Hands Down the best, in my humble opinion, is Spire. (spireusa.com) Absolutely bombroof! Designed BY computer geeks for computer geeks. Very well thought out- I will no longer part with my hard earned $$ for anything else. I used to tear through bags at an alarming rate- going on 1 1/2 yrs with same spire with NO problems!!
They are pricey though- check on ebay etc first...
