One could build your own fairly easily with an adjustable sin wave generator, linear transistor amplifier and a small mains transformer.
What voltage is required by the drive motor?

I've run my C8 drive from a Dick Smith 12V inverter, also square wave output, with no ill effects. There's no electronics as such in the drive, just a 240VAC geared motor.
