A decent system, but don't expect it to be problem free. On switching over to Active Merchant we saw a downturn in payments. The problem was early developers simply trusting that Active Merchant would be problem free. We ended up having to disable the internal credit card validation tests to keep the system from rejecting valid cards. No experience with the shipping component though.
