Need a 1000w 3-way X10 switch

[ed3120]

I have about 750w of lights that I would like to connect to a 3-way switch setup.

I'm looking at the HCM10-1SW, available at:
http://www.smarthome.com/2203WI/Leviton-HCM10-1SW-Enhanced-X10-Dimmer-Switch-1000w-White-Ivory-/p.aspx

The compatible Slave switch listed in the manual is the MS00R-1

I cannot find anyone that will sell me the Slave switch.  Has it been replaced?  All of my searches return the MS00R-10W, but I'm not sure if that switch is compatible.  Can anyone recommend a 1000w 3-way switch setup that is in stock and can be purchased?

Thanks,
Ed
