I purchased the black "spinner" version of this luggage. The quality is great and it is indeed light (just 8.6 lbs, while the rollaboard version (i.e., (non-spinner is even lighter at 7.6lbs). You just have to compare the weight and quality at its price point with the competition and you will see that it blows them away. I actually compared several brands at the local department store. By the way, this luggage (in black) looks just like what you see pilots and flight stewardess carrying on board aircraft. That's perhaps why Travelpro holds itself out to be "the choice of flight crews (and frequent travelers.")

I am happy that I found great value by finding a great quality product at a good price.

Update as of July 2013:
After using the luggage for awhile, I can say that I would definitely prefer the 2 wheels rather than four for the following reasons:

a) It is difficult to keep a 4 wheeler stationary in one spot. On any surface that is slightly curved, it will automatically slide to the lowest point and this is frustrating especially if you just want it to stay put.
b) I find it easier to drag a two wheeler than to slide a four wheeler.
c) The 2 wheeler is 7.4 lbs vs 8.6 lbs for the 4 wheeler
d) I can't justify a higher price for the 4 wheels based on a) b) and c) above.
