Digital BW, The Print

Hi,

So they are all cheap, pretty easy to obtain, and we need just a small
amount, so I just add them all - based on Paul's experience,  I don't think
there is any downside and there seems to be upside.

I note you are emailing from Yahoo.de -  if you need EU sources just ask.

Cheers,

Mike
