I got mine used about 5 years ago. It has been working flawlessly ever since, and i have done thousends of scans since then, Picture quality is top notch. I use Vuescan software, which will run on any windows 10 PC, allthough you will need at least a firewireport to connect it to. There is a Yahoo group dedicated to this scanner, and they state that you still can get fresh bulbs on the internet.
Alass, if anything else goes wrong, i believe that you are in serius trouble, as there are no spare parts or people to fix theese wonderful machines.
If you find one that is working, you must ask yourself the question, "Do i feel lucky today?"
