I own this lens. It is very good (I do not use it because I only do 6x6 and got a cheap 80 Nikon which helps getting bigger size prints)
If the price is correct, you can go for it. You may even catch a deal because as they're lesser known than the Nikon or Schneider or Rodenstock, you can ask for a reduced price ;-)
As usal check for fungus and the like .....
Have a nice day
