That is a fun configurator. A couple of years ago I had a 32'' scale, 5 string (high C) Frog spec-ed out, but I (gladly*) never went for it. Partly because I couldn't get myself to spent that kind of money on something I've never played or even seen in person. There's a very good local bass player that I know who is some sort of Maruszczyk distributor, but I never got far enough along to see what he could do on price.
*I bought a cheap Warwick 32'' 5er to experiment with this idea, and it never gained any traction for me.
