Maycom's Easycorder
I have used the Maycom Easycorder (the version with a built-in ISDN codec) and found it to be reliable. I especially like the audio buffer, so you can put the device into stand-by during press conferences and then release it knowing the previous 5 seconds are also on the recording. A unit witha built-in ISDN unit costs in the region of 3500 Euro.
The unit works on rechargeable batteries, but BE CAREFUL. There is also a small Lithium battery in the base of the unit. My experience is that you must replace that once a year or you will be stranded in the middle of nowhere with a recorder the just doesn't seem to respond. The battery fails suddenly, so if you're not carrying a spare, you'll have to head for a photo shop. Not clever!
