I have had my new Channel Master DVR+ installed for a couple weeks now and am quite pleased with it. I am replacing an old DTVPal OTA DVR from Dish Network (later sold by Channel Master as the CM-7000). The functionality of the new DVR+ is similar but much updated (especially the guide when connected to internet). You must buy an external USB harddrive to get all the recording features. With a 1TB drive you can record around 180 hours of true HD OTA broadcasts (stunning images). Unit has two tuners, so you can: a. watch 1/record 1; b. record 2 and watch previously recorded show.
OTA is the way to go if you can get station signals where you are (mine found around 160 channels in the Los Angeles area).
