Swiss Gear makes quality luggage at a decent price point. Think I paid $40.00 for DGD’s 22” or 23” spinner on sale. Also saw some good ones by American Tourister at the time.
Target’s, Marshall, and Burlington generally carry one or the other line.
What you should look for when luggage shopping no matter the brand:
Tightly woven fabric (high denier)
Well made metal zippers with 2 heads, (YKK is the industry standard)
A two pronged telescopic handle that doesn’t “wobble” when fully extended is useful for future upgrades as it’s easy to hold a toiletry or lunch bag
Side handles that allows you to easily place in an overhead bin. The handles should be stitch reinforced in a triangular or “X” boxed pattern (same for tote bags).
Inside, compartment bags on the short sides (nice when the bags are removable) and a mesh zippered bag on the bag’s opening side are useful.
Personally, my preference is luggage straps that form an “X” but nowadays most bags have side by side straps; easy to modify if you’ve basic sewing skills or access to a decent shoemaker/ shoe repair shop.
I prefer a exterior zipper compartment to hold travel documents and readily accessed small goods so no need to open the main body. A side opening for a newspaper or umbrella might be something to consider as well.
For the same price, it’s been my observation that hardside bags are not as well made. I see too many duct taped or cellophane wrapped aluminum suitcases coming off luggage carousels.
