Andre,
I have the same setup and I am quite happy with the unit. It is built like a tank. I bought it for about A$450. I think that at 100 euros, it is a good buy, if it is in good working condition. Please be aware that L900 only goes up to 6X9. If you want to have the capability to process 4X5 in the future, you will be out of luck.
Cheers,
VV Ramesh
