W/ the new job and flying 1-3 times a month vice once a year, I felt the need for some quality luggage. My old stuff (which is fully functional) is up for grabs. I have a 21" and an 18" (both carry on size) forest green roller peices. the smaller one fits in the larger one for storage.
They have served me well, and i would like someone to get some use out of them. they are not pretty, but will work for your kids, or for you to have a carry on to compliment your seabag!
