[support] is eCommerce viable?

Folks: I am trying out the eCommerce module for an online store. I did this after frustration with trying to set up ubercart for paypal IPN with web payments standard. Do any of you know if eCommerce is a viable solution. I can't seem to find any tutorials on the current version, or any kind of support at all. I'd be very interested in opinions and experience.
