This thread http://www.sawmillcreek.org/showthre...-advice-please and others convinced me to look at Phase Craft and the 10HP and 15 HP RPC controllers.

In several threads here and at practical machinists I've found discussions where posters cite getting good motors in the 10hp and 15hp category for $20/HP ($200 to $300).
But I've found few posts discussing the QUALITY of the motors except one saying Delta motors are poor.
So some questions:
Any recommendations on motor brand?
Where do you find the motors for $20/HP?
I've called seven "Electric Motor" shops in my area that rebuild motors and only found one that sold used, and they had none in stock. On ebay it looks like I'd be paying $25 to $50/HP plus about $100 shipping.
Can I run a 15HP RPC off a 60 AMP circuit breaker? I've got 2 60 AMP breakers in my 400 amp panel and 4 30 AMP breakers.
Do any of you RPC wizards use "pony motors" (http://www.paragoncode.com/shop/rotary_converter/ ) for starting?thanks in advance.starting in-rush current for a 20 horsepower three-phase motor running on single phase power is monstrous.
/edit - for the safety police I do plan on running a 3 phase panel with big enough wires to allow 6 or more drops off the 3 phase panel.
