Last year, when I was a little worried about the availability of spare parts for my ATL-1000, I wrote an e-mail to Jobo in Germany and asked them, and this is the answer I got:
JOBO ATL1000 spare-parts are still available and machines can be repaired by our service.
JOBO ATL-1500 and 4080 Colorprocessor CPP-2 are available ex stock.
So they had spare parts, and the ATL-1500 and CPP-2 available in stock, in 2008. I suggest that anyone looking for spare parts, or a new machine, contact them directly.
