Check out this site, they may have what you need:

If you find something there, make sure you adhere to their rules, when you inquire/order.

As mentioned, Heyboer is an option. I purchased one of theirs, and received it in warp speed time...3 days. As a matter of fact, I mailed them a check, as payment. There is no way it could have cleared, before it shipped.

Good luck!
