I sell on Etsy, the link to my store is in my signature. They are basically, just another daymare, much like Ebay.
However, they only charge 3% seller fee, but they also charge a .20cent listing fee per item. That item stays listed for 4 months. They have recently implemented mandatory direct check-out through their system, so fees may have gone up to 4%. I use them with stand alone Paypal, so far so good. Nothing to write home about, but it makes up for what my CD's are no longer making, lol.
Type into search "alternatives to ebay", there are some blogs that lists all the different selling venues. Dawanda, indiestore, go-daddy, shopify, not really a lot of effective alternatives (that I've been able to tap, as of yet). Good luck.
