This deal has ended.
2nd Update: this has jumped up to $99.95. Amazon now has the Sony XDR-F1HD High-Definition Receiver for $99.95, the lowest price available on the web when you factor in the free shipping you'll also receive. Plus, use this $50 rebate to drop the price to $49.95. This receiver has HD sound which converts AM to FM quality, FM to CD quality, and allows you to listen to the HD channels for no subscription fee. There is no sales tax (except NY, KS, ND, WA).
