Ok, I have been looking at a few Sinns over the last few years, but I may finally pull the trigger if I find a very nice 903 with the Lemania movement. I really like the idea of the H4 with the added moon phase complication, but they seem hard to come by, and I think the Lemania models are the only ones where the sub-dials don't extend into the minutes hashes.

Any tips on reasonable prices would be appreciated; from what I see they can vary a lot. Thanks
