Diaper Bag...what to choose!!!

What diaper bag have you ladies decided on? With my first child I bought a really cheap diaper bag that didn't last long! With this baby I want to buy a bag that is good quality but not too overly priced, something that is great for baby items including my items since I will no longer be carrying a purse anymore, & not too huge but also not too small! I can't decide...I've been looking on Amazon & babies r us but I'm just not sure what to pick! What diaper bag did you get & where?
