I'm VERY interested also.
My criteria would probably be similar to many of you:
--secure purchasing
--simple, elegant website...professional looking
--easy to setup, minimize the need for a programmer or full-time administrator, something a non-programmer can manage (assuming he is comfortable with computers in general, like I am)
--Hopefully, it doesn't LOOK like a blog. I don't want a purchasing website where it's so obviously a shoehorned blog theme. Even if it's on wordpress, I don't want the blog-look to be obvious, if possible.
