Foam for scope case

I'm making a homemade case for my fs 102 and am having trouble finding some grey/black sheet foam to line the thing with, I don't want white as it will just discolor with time. The places I've found online so far are aimed at big users and want a minimum order much more than I'm looking to spend.... any Ideas? TIA, Tim.

I use http://www.foambymail.com/. I've had it shipped and picked it up.

I don't know how much you want to spend but I do recommend them.

P.S> you probably will want to use closed cell polyethylene foam. Great shock resistance and little or no outgassing.

They also sell a Charcoal Foam that is made for cases. It is what they use to cut custom fit case inserts at Foam by Mail. It is cheaper, easy to cut and not quite as heavy.
I use both and they are both great foam.
