Yes Michael - I can definitely understand, and I'm doing my darndest to remain strong and to not succumb to keeping both systems (somebody once said something about the spirit being willing, but the flesh....???).
When I was talking to Frank Marshman yesterday, he of course has seen more than a few of the insides of both of these cameras (I read an old internet posting of his from a few years back, and he said at that time that he'd repaired over 70,000 cameras, which I can't even get my head around!). He doesn't find either camera to be more difficult to work on than the other, though he did say that the Contarex can be intimidating to the uninitiated. The Leicaflex has that 1/2000th shutter speed, which utilizes an additional spring, and he said that adds another level of complication to its mechanism. For him, both cameras are very very good, but holding that Contarex is really something special, plus it's just so unique looking. But, as you say Michael, that Leicaflex has a way of seducing you in very subtle ways, which makes this decision all the more challenging.
Just keep telling yourself Vinny -- be strong, don't give in, don't give in...only one system or the other.....be strong....
