Hmm...which one?

Morning guys, I've decided to add a Rangefinder to my ever growing collection however, I'm stuck between 3 of them: Yashica GSN 35 electro, Konica C35 and Canon Canonet QI15GIII. This is what's available in my area for roughly the same price. I've obviously done my homework on each camera, I know they are all very good Rangefinders however, Google and YouTube can only give you so much and, I would like your opinion please from the wise guru's.

Thanks fellas
