I have an efi America and got a stock set of an 04 of ebay for £30. Then took the last baffle out myself.
It might worth keeping an eye on there for a bit first rather than paying the postage. OK I collected but it would still be cheaper than just the postage from over the pond.

09 America - It's very blue....
