$20 servo motors with encoders

I found some $20 servo motors with encoders,
problem is they are brushless and I don't know of
any hobby-type (ie inexpensive) brushless servo driver boards:

SKC Shinano Kenshi Corp. # LA052-040. 40
Watt brushless servo motor and 6 channel
encoder. 24 Vdc , 3000 RPM motor. 3.471" long x
2.13" diameter. 2.125" square mounting flange.
0.31" (8mm) diameter shaft x 0.85" long. 20" leads
(.pdf docs there too).

Here's the link if anyone can figure out how to use them:

Please let me know if someone knows of a kit or a circuit
to drive them.
