I recently purchased a 21" Skyway Sigma 2 luggage for a trip from NC to CA and back.  That bag was checked along with 2 Skyway Sigma 2 26" bags.  We also had a connect in Chicago during a snow storm in yearly December 2010.  While we were in CA, we also drove from Northern Cali to Southern Cali and these bags hitched a ride in the trunk of our rental.  They all went through a good amount of travel and made it back home in great condition.  No issues to report for any of them.  I feel you get a great product and great value for the price.  I will definitely be purchasing 1 more 21" and 1 more 26".
