I'd try Samsonite. Great quality, expensive, and doesn't say anything about buyer being responsible for delivery.

I've done samsonite too, 400€ doing ftid with ups in Spain

Thanks.. Can I do DNA with them? 

Should i do one suitcase at a time? or can I DNA a 3  piece set?

A word of warning, samsonite has a return fee, $15.
If they ship a replacement and you do a return, it's going to cost at least that.
Not sure if it's $15 per item for a whole set.

In Europe is free the return, maybe you can say that the wheels doesn't work well and you want to return the product and that would be free.
