I finally got my digital tv converter box. I ended up getting the Insignia NS-DXA1 at Best Buy. It is just a rebranded Zenith DTT900. I used a 10% off coupon (search for Best Buy 10% coupon) and one of my $40 government coupons (more like a debit card actually) so I ended up paying less than $18.
After installation and initial setup I now receive 9 channels verses the 5 I received over analog. The extra channels are all subchannels (2 PBS, The CW, and 1 local) of existing stations.
Picture and audio quality are very good on my aging 19" TV. The remote works great and can turn the TV on/off. Volume is controlled by altering the audio stream (like changing volume on your computer when your speakers also have a volume knob). You set the TV's volume to mid range and leave it. The only downside is if you pop in a DVD you might get an earful at that volume setting.
I get good reception with a cheap indoor antenna though I'm only 15 miles from the transmitters.
I'm glad I spent a few extra dollars instead of getting my other option (the RCA DTA 800B at Walmart).
