...and Magento would NOT be on my list.
Not just because eBay bought them last month, but because in all the times I've tried to review it for customers I've had to jump through hoops just to try to get a copy running.
I've downloaded and installed dozens of ecommerce packages, (or registered and setup in the case of hosted package), and if you can't set it up in 15-20 minutes and build (1) $1.00 test product and be able to test adding it to a cart as a user -- it's either overly complicated or poorly documented.
My $0.02 --- steer clear of Magento.
