Yes this is the main problem I had. Other rangefinders may be smaller, however they do not have aperture priority. The Yashica does pretty much meet all my needs, and I'm willing to sacrifice a bit more bulk for that. Currently I have a 5D and a FM2, so hopefully it won't be as bulky and heavy as those!
And yes, I did take a look at cameraquest. It is really fantastic!
Bigger than an FM2 with a compact 50 I'd have thought. They really aren't at all small.
