Yow, well, I would hope that an $800 handbag would be made well and you're buying quality and not just a designer name.  But I doubt you could tell until AFTER you had the handbag for a while.  
Yes, I've had a bag made by the same designer (several, actually) since the 70s and they are in excellent condition.  If my daughter and niece hadn't already claimed them, I would put my vintage bags up for sale on Ebay.  I may sell a few of them, but I haven't decided yet.
My sister didn't even blink when she put down $860.00 at the boutique for me to get that bag for Xmas.  But she says she'll never buy one for herself.
Del, I love, love, love your avatar picture!  Gorgeous!
