Had a look at another of my purchases from the St Neots rally. A small box of Japanese consumer electronics. I immediately paid the £2 asking price without even digging into the box. Why? Because I could see that there was a Sony Video Walkman in there.
Emptying the box produced a GV-D800E, 3 GV-U5Es, some chargers/PSUs, battery and a NIB 30mm 2x teleconverter.
The GV-D800E is a 8mm/Hi8/Digital8 Video Walkman in a clamshell design. It records and plays composite video, S-Video and Firewire (DV IEEE 1394). Set it up and it all works perfectly, digital and analog.
I'm going to flip this one as I already have one. Because they are so useful for dubbing old camcorder tapes to DVD or computer and the camcorders don't seem to survive, these are in fairly high demand. There is also a niche market for people who need to record analogue video. I expect to make at least 100 times what I paid based on recent sale prices. Some ebay asking prices are insane £600-1000.
The GV-U5E is called a Video Walkman but they have no display. They are Video 8 record and playback only. All three seem to work
I Think I'll keep one to record the output of my WASP thermal imager. Less faffing around than a laptop and USB frame grabber.
