I like pre-loved, but I know some people prefer brand new (okay, I love brand new, too, but it's so expensive! And I know after repeated use, the resale value goes down).
I think pre-owned is a good option since:
A nice condition one can be really cheap
A nice condition one will have patina so you don't have to worry about the vachetta bottom)
If you change your mind about the noe in the future, you can always resell it without much financial loss
Brand new is good also since you get to patina the bag and it smells nice (hehe). And it's nice if you plan to have the bag forever...
I love the Noe (both regular and petit). I was never a speedy gal, and I don't think I ever will be...guess my collection will never be complete since I don't have (and don't plan to have) a speedy.
