I think you would be very lucky to stumble on one. There are used ones on places like e-bay and others, but I think the true fans have snagged all the new ones that come up and have driven the price through the roof.

I think the only way you will find them for a decent price is to walk into a store that still has one on the shelve for some reason.

If it's for yourself, it would sadly probably be less expensive to buy a 220 one, and have an electrician wire you a 220 outlet for it than to buy one of the $500 ones.
