Good luck.

Finding one of these on the used market is going to be next to impossible considering they're still relatively new and I still can't think of a single MDD owner who has bought one.

You might look into snagging a Dual 1.42GHz MDD CPU from eBay. It'll be significantly cheaper than Sonnet's MDX and provide nearly the same level of performance because of its L3 cache.
