I have this bag and ABSOLUTELY it! One of my favorite bags! There's one on Let-Trade right now (I got mine from there). I personally wouldn't pay the outrageous prices on Ebay!
I see a lady in the grocery store every so often that has that bag. It is a great one. I remember being in Vegas and seeing it there too when they came out.
Good luck finding one.
I own the Mono Mizi. LVOE, LVOE this bag! I believe the retail was approx. $1,300, but correct me if I'm wrong. I purchased it via Let-Trade for a lil over retail. Worth every penny!
