Many thanks to SWLing Post contributor, Mario Filippi, who points out this Funcube Dongle Pro Plus with a BuyItNow price of $100 on eBay. The seller appears to have a long eBay history and a 100% rating.
Mario and I were both tempted at one point to snag the Pro + at this price, but neither one of us needs another SDR. Please, someone buy it before I change my mind and buy it in a moment of weakness! 🙂
