I just checked them out on eBay. I seached for mg995, then limited the seller to tesla_electronics.

Here's a direct link to one of their listings: [link=http://cgi.ebay.com/2-x-MG996R-Metal-Gear-Digital-Torque-Servo-2BB-MG995-RC_W0QQitemZ390152000083QQcmdZViewItemQQptZPCC_Dri ves_Storage_Internal?hash=item5ad6df1253]eBay link[/link]

EDIT: Actually, the above link is for the newer version, the MG996R, but they also have listings for the MG995.
