I'd also check the static model joints, too, like squardon.com and scalehobbyist.com, etc, etc. Even places like hobbylinc, since decals fit in a simple envelope it opens the options. Of course, I did once order decals and they showed up about two months late with a literal tire track (I think from a forklift) on the envelope and about 25% of the sheet was no good. I probably even still have that sheet ... somewhere.
