I went to Best Buy, hoping to find a 260w at a resonable price (for my wife's car). They didn't have one. Some cute little informed shopper girl had a HHGreg price for the newer 255w at $149. Best Buy's price was $199, but they matched her $149 price...I jumped in at the same price.
The 260w is history, hence the low price. Thanks to the cute girl, I got the newer model with more features for the same price as the obsolete clearance model.
Thanks, cute girl.
