Suggestions for hops rhizome source?

I want to plant a few hops rhizomes this spring. I'm in East Central Alabama and have read that cascade is probably my best bet. I see folks giving away or selling inexpensive rhizomes on this forum- what are other good source(s)? My local nurseries/hardware stores look at me like I'm crazy when asked if they carry or know of a source.
I'd prefer to buy in person- I travel to the Atlanta GA area often. But mail order would work too.

Thanks,
Mark

I had a great experience this past fall with Great Lakes Hops. Even with the shipping to GA everything was quick and they even packed a bonus plant. I went with crowns to get an early start last fall to be ready for this year. They grew almost 6 feet even in the late fall and have already started sprouting this year.

The Hops Shack has them also, and good prices:
