Ask HN: Online Shopping Carts? Is Satchmo any good?

I am looking at setting up a shopping cart solution for my day job and I came across Satchmo ( http://www.satchmoproject.com )

Has anyone here used this with any success? Built from Django it looks like a pretty robust, well engineered, and modifiable system. Though, I would like to hear from some of the people in the field that have used it on a production server.

I used Magento in the past and found it to be a pain to modify the templates and it broke things into so many files that the sites built with it are pretty slow out of the box.
