I DO!
I have several stores and they are ALL successful!
Check my website link out.
http://www.southernjewel.com/
When you get to that site, you'll see my links on the left hand side. Those point to a few of my ecrater stores. (Ill be working on an oscommerce store, I hope)
There are no hidden fees, no major issues that I know of and I've had stores there since last spring.
My experience has been positive.
The only problem I have is that Dimitri, the owner, just instigated a feedback process.
What I don't like about that system is the feedback link is on the Paypal receipt for feedback to be left right then and there.
This opens the door for fraud for the seller and more. This is discussed on the eBay Store Discussions in full by many ecrater store owners. I'll try to find the link tomorrow and link it.
But besides that..I'm pleased with ecrater. The site feeds to Froogle/Google and your listings are in the Google seen with others.
Best of all? No fee's to eBay.
Good luck and if you need me, email me.
