Personally, I think Baldas are folder sleepers. I have four folders, and my Balda Hapo 66e (a department store model) is by far the best. I'm taking it with me this weekend to LA loaded with Ektachrome 200 (120). I do have to say the pedestrian Agfa Isolette II is also pretty good (rugged). But the Balda has a built-in uncoupled RF which is really nice.
You seem to be having a great time with yours, good luck with it.
