There is at least one Yahoo group dedicated to these tuners as well:

Subject: Cheap Fun with the RTL-SDR

I picked up an RTL-SDR at the Timonium hamfest for $20 and found it was most useful.  It was originally made to tune European TV and seems to have been made in the millions.  As good AMRADers we enjoy using them differently from the original design.

Essentially it tunes from 60-1700 MHz when plugged into my notebook computer on which I run the software SDR#.  On further search there is a bunch of data out there.  I did a Google search on

Realtek SDR RTL-SDR Receiver schematic 

Here is some useful info on the dongles I came up with:

Search on eBay for rtl-sdr and you can find them for $10.16 with free shipping.  I bought one under the title:

ON SALE! Practical RTL-SDR FM+DAB DVB-T Dongle Stick RTL2832+ R820T SPC-0155

This is indeed cheap fun.
