Hi David,

Picked up this thread late - as usual. I used these trickle systems (http://www.photomart.co.uk/ProductDe...roductID=31261) when I ran a hand printing lab, I found them v effective. They deliver the system, you use it for about a year and they come back and replace the bottom bucket. They keep the revenue from the silver recovery but it leaves you with a clear conscience - that you aren't throwing silver salts down the drain. 60 per year didn't seem a bad price to pay.

I was told by Photomart that they were imported from the US.
