I've found that Ricci transformers are good for Tesla use, being very solidly built. The GFI is in the lid not the transformer itself, and they can either be trivially bypassed, or you can get a non-GFI lid "for use with external Earth Leakage" (or in our case none at all!).
Sign-tec (to whom my only relation is as a frequent customer) are very helpful. http://www.sign-tec.co.uk/products_list.asp?catID=2&prodGroup=Ricci+Transformers&subCatID=9 . I can't see it on their current webpage, but in past years I've purchased a number of 10KV 100mA units without any problems.
I've also ordered from SignBuyer with equally good results http://www.signbuyer.co.uk/ricci-neon-transformer-2363-p.asp , and their website lists the full range of voltages and currents.
Hope that helps,
Colin.

Hah, thanks. I was going to ask if anyone knew if the GFI's on these were easily disable-able.
Cheers,
