I don't think quality is restricted only to premium designer bags. I have been disappointed with the quality of some designer bags, and impressed with the quality of some non-designer bags. I look for what I like and what is well constructed and stylish - whether it is a designer or not. After seeing a lot of designer bags that are just not worth the price, I find myself actually more open to look at other bags.
Amen!
When one really knows quality, then one can find it in a variety of bags.
