Default where to buy ei cores for ot and pt

I have been trying to find a source for ei laminate, but all the places i find are requiring I buy in 1000 lb increments

So if anyone on here winds their own transformers, where are you getting your cores?

Any help is appreciated

I live in Seattle. I have a couple 100w trannies and 300w trannies I need to build. I haven't figured out exact tongue size yet due to limited sizes available that I have seen so far.

Theoretically to get it to be closest to square I would need tongue sizes of 72 mm and 55 mm. That's based off calculations for proportions of a waste-less core.
