I received my RTL2832u with the r820t tuner, and so far working with it with SDRSharp - I have to say I am pleasantly surprised by the performance of this $19 dongle - even with the stock antenna.
I purchased this dongle here on Amazon, and it arrived pretty quickly:
Amazon.com: NooElec TV28T v2 USB DVB-T & RTL-SDR Receiver, RTL2832U & R820T Tuner, MCX Input. Low-Cost Software Defined Radio Compatible with Many SDR Software Packages. R820T Tuner & ESD-Safe Antenna Input, Guaranteed: Everything Else
Here is what it looks like hooked to my WinXP decoding machine.
