http://thekindlewarehouse.com/kindle-2-covers/ mentions a Kindle2 cover that I hadn't seen before.
Bobarra is the maker/brand. see

They have 2 different styles of leather cover (each in several colors). One with no closure, one with a tab closure similar to M-Edge's, and one with a magnetic closure. The price is comparable to M-Edge --- and I'm tempted!
Oh, but no "amazon hinge" connection to the cover.
They seem to have less extra space at the spine (where M-Edge is leaving room for their light). That extra space is putting me off the M-Edge covers, since I don't want the light.
