Will,
Does it cost any more than it cost before as a new model, now that it has DPL-II?
From what I've read, Anthem said that they would increase the list price of the AVM-20 by the cost of the upgrade: i.e., $300. However I don't know if they've actually gone through with it. Besides, if the dealer discounts it to a price that's comfortable for you, it may not matter what the MSRP was.
(BTW, was in your neck o'the woods yesterday: jury duty at the Santa Monica courthouse. Blech!)
Best,
Sanjay
