For processor, I prefer a simple one. including the design and machine itself.
"Glunz&Jensen" is a very good processor but too expensive and too complicated
"Grafmac" processor is a simple one with enough function
"Huq" processor OEM for Kodak until now(in some region), the quality is also OK
“Heights” also very complicated but the quality is not as good as its price
"Sirio" ..... it can work, just can work.....and i don't like it.
Hope it is helpful.
