Good deal! I picked one up for $225, although it looks slightly less used than yours. It was labled Obel, though. I found that the hopper was chipped on the base, and so it does not stay fast. I ended up removing it, mainly because it is too tall. I just dump the beans in and cover it with an upside-down blank filter.
This grinder was a welcoome change to my Vario, which seemed to not be very stable. Sometimes, 12.4 seconds on the grinder would give a 17 second shot, and the next would take 60 seconds. The LP is consistant, and seems to giver better tasting shots.
