I'm looking for a small messenger bag that holds a mbp 13 and an iPad in a dodo case and maybe a ouple pens and charger/cables for the mbp. I'm using a 15" messenger bag and it's just too big for me. Any suggestions. Preferably under 100 bucks?
One of my favorite case/bag companies is STM Bags (http://www.stmbags.com) I have their medium Evolution backpack for my Macbook Pro 15 and I bought their small Alley Shoulder Bags which is designed for a 13" MacBook/Pro. I use it when I want to take my Alienware M11x (since the M11x it a bit huskier than the Mac's it fills the pouch just the same- i.e. perfect fit) and it has a perfect slot for the iPad as well. They also have some Backpacks with iPad specific slots.
Their stuff is Very well made. I've only had one problem with a backpack a while ago and they sent me a new one- This was after I'd been using it for 2 years!

I couldn't recommend STM's bags any more enthusiastically!
