We've got a Panasonic one.
One of the great features is when you use a DVD RAM disc. You can start playing the beginning of what you've recorded whilst it still records the end. (Does that make sense)
You can get 4hrs on Long Play onto a 120 disc. And the qualities pretty good at that resolution.
Get one, but dont pay a fortune as in 1-2 years we'll all need to buy the dual LG player/recorders (The ones that do BLu ray and HD DVD)
