Is there any good online sites where you can order Bamboo plants from?

I ordered from www.bamboodirect.com last year.

I knew that the bamboo that I ordered (clump-type) is marginal in my
area (zone-6) (as warned in their web site). But I ordered anyway. I
plant them last fall, and they all died during the winter. The lesson
is: If the web site says that the bamboo is only marginal in our area,
we may not want to try it.

Will I order from the web site again? Sure, I will. But I will not
order anything that are rated only marginal in my area.
