Saw these on ebay.

Getting wife aggro at the spiderweb of cables so probably going to hold off for the time being. $250 for a P2P connection is wicked though.

This is not a bad price for the Connectx 3 EN -- $199

An X-3 EN with dual QSFP connectors (10 and 40 GbE) went final bid for under 200 yesterday.

There are some X-2 EN dual SFP+ (10 only) for under $100 right now, really cheap way to P2P three computers
