I just purchased a great carry-on tote from Kohls..
I was looking for a nice tote bag to match my new luggage, and I found this bag orginally at ebags, but got it cheaper at Kohls. Less than $30 including shipping. Its comes in black and brown. I ordered the brown.
It really expands to a large size too and looks like it will hold plenty.

Years ago, I bought one on board a Carnival ship. Expands like this one and has 4 wheels on the bottom. I use it for everything! It is just tall enough when expanded that I can pull it using the handles. Learned to pack heavy stuff on the bottom for stability.
