Most expensive custom 1911?

What is the most expensive custom 1911 you have ever actually seen? Did you think it was worth it? I am not talking historical pistols here, but the works of art that are actually used by shooters not gathering dust with collectors. I am curous as to how bad (price)/good(form and function) the things really get. If you have a pic, by all means, post it please. Personally I have only dealt with Wilsons so my experience tops out at $3000. I would not be surprised to see some of youse guys to come up with examples 5 times that amount.
