Wow, this is a long shot
I have recently bought a Dedicated Micros 16 channel CCTV DVD recorder unit.
It was only when I went to collect it (by which time I was committed to buy) that I realised that there wasn't a PSU with it.
Anybody that has any contact with these things will know that the PSU's are a very complicated and expensive item.
I will be ringing the UK offices of DM tomorrow, but just thought that I'd 'speak' to you guys first.
Thanks in advance / anticipation
