Cheap and Easy SDR  Time owned: 0 to 3 months
Per the Jan 2013 QST article re Cheap and Easy SDR, I decided to give one of these DVB-T units a try. Mine was about $25 plus ship off Ebay, and contains the RTL2832 quadrature sampling decoder, and the E4000 tuner. I'm using SDR# set up per the article, except that I found the SDR# Config file entry for RTL-SDR/USB already active. Only other gotcha is be careful using Zadig when installing USB driver, or you'll be reinstalling printers, other USB devices.

Anyway, while the noise floor is around -70dbm eg on 2M using a yagi, for the money, this is a cheap and valuable introduction to SDR, SDR# is a free download.

My version of SDR# does allow gain adjustment or let it be handled auto by AGC. I found +10db manual gain to be about right for my setup.

I also operate a Softrock Receive Ensemble II and SDR-IQ, albeit both on HF, and with noise floors on the order of -120dbm or better. However, the described DVB-T will get you on approx 64mhz-1700mhz, at little up front cost. Also comparing a NF or floor on HF vs VHF/UHF is not really apples for apples. A good antenna is a must, and the supplied antenna is not. The antenna connector on my DVB-T is a PAL, so series adapter required to F or UHF.

The QST article went on to describe an HF upconverter that could be used with the DVB-T, but by time you build and pay for that, could build and pay for one of the other SDR kits designed for HF, get far better performance.  
Product is in production.
