I found press releases for 3 more DVD Recorders with ATSC tuners. One from RCA
(who have also announced an ATSC tuner for old analog TVs) and two from Samsung
. They are all going to be in the $250-$320 US range and will be available in the middle of 2007.
Edit: I also found Panasonic's press release
. It looks like all of their DVD recorders in 2007 will have digital tuners (other brands entry level machines seem to lack any tuner).
I should also note that all of these DVD recorders seem to record in either EDTV or SDTV but not HDTV.
