I have one of the Joanne's bags w wheels I bought it when they had it on a real good sale. It doesn't have any padding inside the outside has a zipper pocket. I think the one for $29. looks a little sturdier maybe.
I don't know if you could get a suitcase with wheels for under $29. but you can always ck the stores have so much on sale lately. good luck finding something you like.
I agree with you Pilgrim that things made for quilter's are higher priced sometimes like you say you can find things in other departments work as good. Sue
