I see the Go-HD and the Go-HD + listed but not the A-HD. The A-HD was listed in Dec but was removed from the list in Jan. for some reason. Maybe Aiptek were getting swamped with emails for this camera. In any case I've emailed them about 5 times now and never got a reply once yet. Only once I got a reply from the tech guy in Taiwan as I explained to him that they don't reply to my emails here in the U.S.
I like the idea of modifying the camera by removing the mic off the board and soldering on a 1/8 mono plug. Then modify a 1/8th jack by soldering on a better quality mic anduse a little heat shrink to make it clean. Then I have the choice of a corded mic or a plug-in mic as I just described above (uni or omni) depending on what I'm recording. I may do that...I'll see.
