Which Portable AV recorder do you use ???

HI all,
I've been using a Sony GV-A500E Hi8 Video Walkman as a recording, playback unit on my bike but it's no longer working. I was wondering what are my alternatives, If any?

I have 2 cameras switchable, mounted on the bike. Either camera together with the audio from my autocom headset was been recorder onto my existing unit.

My needs are;
Minimum 90 min recording time.
Bike powered (with adaption if necessary)
Playback screen.
Reasonably robust and not affected by vibration while on the move.
Separate audio and video inputs.

Please help.

Bump.
Anyone able to help me with this query please ??

Haven't got one but search internet for Dog Cam....

I used to do a air bit of in car stuff and used a little MobiBox SD recorder



Doesn't meet many of your requirements though (it's rechargable battery powered, and has combined video/audio input). Always worked well for me though.

For bike stuff I have started to use a GoPro Helmet Hero rather than and on bike cam.
