My Travelpro Crew series is on year 5 and I've only had to replace the wheels once. I replaced them with the inline wheels, as they are much more durable. I've had the zipper pulls replaced here and there as well. I still have not spent what one of those metal frame things cost.
Don't believe the hype of the $300 bag, $1000 headset, and $300 sunglasses...better things to spend your hard-earned money on, like shirts!
