There is a new online marketplace for artists: Zibbet.com. It's scheduled to go live from October this year.
According to the information page sellers from all over the world can register their art for free. A flat rate commission of 20% will be charged.
You can pre-register now. If you're a fine artist then I think it would be good to get in on the groundfloor. I think a lot of the first sellers on Etsy have done really well. Personally I would read the fineprint very carefully (see the footer) and note that the payment arrangement is different from Etsy.
