Yes I have one! My first rangefinder. I had to free up the shutter with some lighter fluid, it was a little bit of a sad case, but it's a very solid and reliable camera on the whole. The lens isn't the fastest (f2.8), at least compared to my Lynx 1000 and Electro (but the Electro doesn't feel anywhere near as nice in your hand as the Minister D); however the camera is solid, shutter is light, you can easily hand-hold shots at 1/15s.
The cool thing about the Minister D is the CdS meter (just use a hearing aid battery) which reads much lower light than the selenium meters on the other Ministers and the Lynx 1000. You get a LV number off the meter which you then set on the outer ring on the lens; this gives you a aperture/shutter combination which you can vary all the different combinations, whether you want a fast shutter speed/wide open lens or a slower shutter speed/big depth of field. Some people whinge about these types of meter setups but I find it very useful, it doesn't lock or anything so it's very fast and you can bracket just by moving the LV ring. I find the CdS meter quite accurate and it seems to have a narrow-ish angle of view for its type which is helpful in certain circumstances.
I think it's great and aside from the slower f2.8 lens I reckon it's a far better camera (esp. build quality and `hand feel') compared to the Electros.
The stuck shutter could likely be fixed very easily with some q-tips and Zippo fluid, just unscrew the front of the lens with an old mousepad or something. Easy!
