Amazon offers Prime members the iView MiraDongle Streaming Media Player, model no. iVIEW-100MD, for $10.99 with free shipping. (Non-members can spend $35 or more for free shipping; otherwise, it adds $8.02.) That's $9 under our April mention, the lowest total price we've seen, and a current low by $12, outside of the price below. It streams multimedia files from an Android device to your TV in up to 1920x1080 (1080p) resolution.
A close price: Newegg has it for $1 more. Note that Amazon is temporarily out of stock but it can be ordered at the price above for delivery when available.
