I bought a Cardwell 500PF 3.5KV on eBay last year. As a bonus I discovered that it had a reduction drive when I opened the box. :)
Not sure if it fits your requirements - it's pretty ratty looking, and was obviously pulled from some electronic equipment. I sort of resigned myself to needing to 'spiff it up'. Keep your eyes open on eBay, that's the best advice I can offer.
