I got mine from Wholesale Hunter on GB. They had 7 1/2 and 5 1/2 models. You might try Texas Jacks, that is Cimarrons FFL in Fredricksburg, TX. They can ship to your FFL and avoid fees and state sales tax.
Thanks for the responses.
And 44caliberkid, thanks for those leads. Neither of those places had any SAAs in 32-20, but Texas Jack's, who I had never heard of before, has another great gun that I may just have to get for myself!
