Yeah, a DECserver 500 or 550 version of an M7554 is usually the least expensive version to find. Here are some asking $175.00 or make an offer. http://www.ebay.com/itm/DEC-KDJ11-SB-M7554-PB-DECSERVER-500-18-MHZ-CPU/111708401901 I picked up a couple of the DECserver 550 version (1.5MB RAM instead of 512KB) for closer to $50 each, but that was several years ago. The 11/53 version without the S-handle bracket seem to be a bit less common. I managed to also grab one of those on eBay a while ago, maybe less than $100 at the time.
