Which multi vendor is good in your option?

Can someone who have use a multi vendor tell me which multi vendor you using and is it good and easy to use.

Thank you

This is just to add the magic word "mall" to your thread, since OC mall or OC malls may occur to people before multi-vendor(s), in searching or thinking of answers. The malls I've seen have not been encouraging in their lack of ways to limit participants' admin and other mistakes (many partipant vendors won't read or remember any instructions).
