Whatever I could afford. For example, if a $300 bag put a strain on my budget, I probably wouldn't get it. But if I had enough to pay for a $3000 bag and not have any financial repercussions, then I would look at something a little more expensive. Right now I'm not making a whole lot of $$$, so I won't be dropping $3000 anytime soon. Someday! (fingers crossed)
There is a limit for what I would consider absurd. I probably won't own a Birkin. Cost aside, the bag doesn't speak to me very much, but that range is a little ridiculous imo. I dont' think I could ever bring myself to spend 10,000+ , no matter how much I like the bag.
