Check out TJMaxx and Marshall stores. Depending on demographics, inventory may vary.
Check out Kipling-usa.com travel bags. They usually have a good sale.
I got a 22" two-wheel rolling duffle. Approx 5 lbs. (Or, check out other travel merchant rolling duffles.)
Depending on how you pack, you may get a bit more room with a Kipling product because, while sturdy, the material is malleable.
Wal-Mart sells American Tourister "rimless" packing cubes. This affords more play in corners and stacking. They come in a set of three - S,M,L.
I used the duffle for domestic carry on - no issues for OH. I put my coat in a new garbage bag and laid it atop the duffle.
For an international flight, I
checked it. No issues or damages. Actually, it doesn't even look 22." When I went to retrieve it, the handler chuckled, and remarked how "tiny it looked." I checked that because I was taking extra stuff for my Italy trip.
My next suggestion is check out Macy's.com and the physical store.
They sell Travel Pro. Check out the "close outs." Don't let that deter you.
I got a terrific deal on brand new 22" Travel Pro Walkabout 3 a few years ago. I got Blue and a Purple (to keep on hand.)
Macy's honors the same return policy regardless of close outs or sales.
Both luggage pieces were on sale, and I had an additional percent off - one came to about $50. The Purple was a bit more. Point being: if you like them, keep checking for the deep discount.
The Walkabouts offer the bigger, "rugged" rear wheels which I prefer. The cobblestones of Italy and I presume (EU), are kinder to the ruggeds.
Overall, the luggage is very lightweight yet very sturdy. Good interior space. The telescopic handle is good also.
I used the Blue on my trips to Italy - as a carry on and as checked - the checked came out on the conveyor with no damages to the luggage or my liquid purchases - fully in tact. [I bring sheets of bubble wrap to wrap jars/bottles before I wrap them again in clothing. Most merchants in Italy will bubble wrap fragile items.]
The Walkabout 3 fit in the OH of British Air. I can't offer experience in a smaller or more budget airline.
Travel Pro Walkabout 3 is sold out. They now have on "close out," Walkabout 4; choice pieces with the larger, rugged wheels. They also have a 17" 'underseater.'
Adding: I think "spinner wheels" can add to the problem of not fitting in the OH properly. Feet first longways.
I've seen travelers put luggage sideways taking up too much room. FA then has to come and rearrange; especially if it's a full flight.
Another tip you may consider: Bring duct tape. If you're traveling multi city and multi country, it can come in handy.
Wal-Mart used to sell small travel rolls in every color. I stocked up, lol, they were clearanced out.
If interested, you might still find them at Michael's Crafts in primary colors - coupons accepted.
Ex: On my black Kipling duffle, I put bright orange strips in strategic places - hard to miss in baggage area. Airport personnel thought it was a good idea, lol.
Once, walking through Termini in Rome, there was a man whose luggage handle broke. I had a roll of black in my day bag. With the help of a bookstore associate, we used a couple strips to secure the handle until he got to his destination. He made his train on time, haha.
