Stylewise, I'd have to say my Contax IIa, and it's fairly easy to operate, but the viewfinder is a bit squinty.
And then there is my Olympus 35RC. Fine little compact, and great results, but I don't like the aperture ring placement.
Lately though, it's been my Ricoh 300 that I repaired (well actually, I repaired the other two also, just not as extensively). It's just the right size, nice large veiwfinder, and decent controls. It only goes to 1/300 on the shutter, but then I like shooting 100 speed film anyway.
