Big diaper bag suggestions ??

I've always loved big purses, well now that I have a baby.. my diaper bag will double as my purse too. What bag do you ladies suggest under $100. I prefer the bags rather than backpacks. 
I currently have a black fisher price one that I got from my baby shower but I just feel it's not big enough and doesn't hold a lot. It's also kinda bulky for how much space I don't have lol
