Well drat. But it does look like Li-ion is getting incrementally cheaper with every passing day. A $10k loan to get started for a 75 mile pack/management/charger is still a barrier. I wish I could get the same rates as I could for a car loan but it's really hard to convince a bank that they could repossess my battery :)
