I picked up one a couple weeks ago for $275 including it's original Kreisler bracelet (seems not as common as the JB version).
Really clean, no major bezel damage, a very nice dial was hiding under the original extremely crazed crystal (thanks again
@JwRosenthal). Waiting on a new rotor axle to arrive but otherwise it was a lucky find on the bay. Deals are still out there if you are willing to clean something up a little.
This is the second one I've owned, sold the first because of a damaged bezel that I knew I didn't want to deal with.
