I use my LL bean touring bag as a purse/diaper bag. It has a side pocket for a water bottle and tons of pockets. They sell the exact same bag with a changing pad for more $$, so technically it is a diaper bag I guess. It's pretty big for a purse, and I've been trying to change over to a nicer purse for myself, but it's hard to let go of the big LL bean bag for running out of the house with everything in it. My compromise has been to put a few things in a nicer purse when I go out by myself.
