zorki 1 or zorki 6 (zorki 6 have longer rangefinder base and more modern design and loading) if you want really small camera. and if you want more quality get some early kiev 4a. also fed 2 can be great compromise between all those cameras - long rf base , pretty small, easy film loading, good vf with diopter adjustment. you can also put industar 22 on it and make it more compact. 
hope this helps
