I just got a Joe Rocket Manta tank bag off ebay. It was $38.50 including shipping! Great price in my mind. Its not very big, but I didnt need or have the room for one on my bike. Have not had the chance to use it yet *&^%$#@ rain. Its got enough room to carry my lunch to work, which means no more back pack. Plus it includes a rain cover and a shoulder strap, so it can double as a small carry bag. And it just looks cool.
