From Consumer Reports:
1) Panasonic DMR-E60 550.00
2) Samsung DVD-R4000 500.00
3) Panasonic DMR-E50 500.00
4) Sharp DV-RW2 500.00
5) Magnavox MDV630R 450.00
6) Phillips DVDR 75 600.00
7) Sony RDR-GX7 800.00
All of the above are DVD recorders not HD and are rated as excellent.
These are from my local paper and are HD TiVO:
Circut City:
40hr TiVo HD (TC240040A) 199.99
80hr TiVo HD (TC240080A) 299.99
Panasonic 80GB HD DMRE80HS 699.00
Best Buy: (both have TiVO)
Toshiba SD-H400 80Hrs HD also has CD 499.00
Pioneer DVR810-HD 80hrs. 999.00
I believe that you need the service when using TiVo or Replay and it's usually between 12.00 to 15.00 / mo or 299.00 liffetime.
The DVD-R models you use like a VCR and record as you want to with no fee.
