here a link that was recomended....but I've never dealt with them;http://www.makincasing.com/mm5/merch...ategory_Code=1
I'm local to them and will try them when the time comes
I just bought some things from Butcher/ packer with ready good results with shipping costs and fast delivery.
The Sausage Maker for me is the best cause it's only a couple hundred miles away and I usually get it 2 days after i order
Edit; Dang just reread your post...thats a lot of casing,try Syracuse casing then butcher/packer , the sausagemaker wouldn't be competitive.
and Let us know what you end up with and how it works out for ya!
