Just my opinion, but about 9 months ago I had to get a new one too, and I went for a DVD recorder/Video, which was very reasonable at about �150. It Plays video's, records video's (standard and long play, but up to 8 hours only,not the super long play of 12 hours, and it records DVD's at up to 6 hours. Plus you can watch one while recording another and if you really want 12 hours recording, nothing to stop you doing 8hours on video and the rest on DVD.
I have no complaints about the quality at all (mine is a Daewoo BTW), and I have copied tape to DVD and vice versa. But, just a comment, you say you have loads of tapes to watch - if these were recorded on a 12 hour tape, even with another player which plays for 12 hours, you MAY not be able to play them - quite often it is recommended that you only watch such tapes on the machine that recorded them, as playback quaility can't be guaranteed.
