I've been using x-cart for many years now. It's still working well.
I just wanted to try the new Ecwid and I was really impressed how easy it was to setup and create online store. It took me about 6 hours (going through the settings and creating first 12 products for sell):

I hope there wouldn't be any conflict between x-cart session and ecwid session.

Have a nice day!
