I just checked the
http://www.ecost.com web site. They do have the Pronto for $279.99 but you only see that price when you click on the "Buy Now" icon, when you do a search on "Pronto" the listing that comes up lists the Pronto at $399, so don't be scared away by that price. (I think their webmaster should fix this, duh!).
BTW: They price for the charger is $51.75
Personally, I got my pronto for $279 with $15 shipping from
http://www.wholesaleconnection.com but they are out of stock at this time.
