An Eden would be up there on my list too. I've heard mixed reviews & would love to see what my personal review would be.
Also, I think these are different enough that people would love to try them:
Colibri
Napsack
and then of course, a few of the lesser known style carriers that people may not have access to as freely: podeagi, onbuhimo, bei bei
Just my 2 cents :)
HTH!
