We love our local TJ MAxx for good luggage deals-- DD got an ultralight tilt-roller and I got a spinner bag. The spinner hard-shell is heavy (~8 lb) but it protects items inside very well. For DD's size, though, that tilt-roller bag was great. Her fully loaded bag only weighed in at about 32 lbs. Empty, that one is only about 3lbs. I think we paid $45 for it at TJ Maxx.
The other thing that I loved is that both of our bags are SO distinctive. Very bright and colorful prints, so easy to pick off a baggage carousel.
