I sometimes use a sony minidisc. Drawbacks with some are automated recording levels.. mine is a simpler beast, what you set is what you get, but remember a torch to light the menu screen!!
Drawback is sony's proprietry file format. There are some music editors programmes that 'rip' the digitised audio 'out' so to speak, or just play it 'in' to the computer in analogue form.
I'm currently playing with a 'Fostex' VF digital multitracker, with also burn's straight to audio CD... but got mine on e-bay for half price!
