Just a reminder Costco has a really nice Kirkland 22" wheelie that will expand 2"-3" with the tug of a zipper for about $89 (about 1/4 the cost of the Tumi, H'mann, B&R etc). I can confirm their lifetime guarantee gets 100% of your money back (I had a minor cosmetic problem), so I returned it, got my money back and immediately rebought another one from them.
