I Just got rid of my 22" purdy neat bag.....It was heavy, not very flexible, and falling apart after 4 yrs. I got a 22" travelpro crew 5 (closeout) from the luggage factory for $107 including shipping. It is lighter, more ergonomic and it expands.
Not sure about how durable it will be, but at 1/3 the price of PNS bag, I figured I'd give it a try.
