I love the Yashica GSN. It is a great little camera with a great lens. The Olympus XA is a decent choice also, and is very portable. I see no real reason to have to "upgrade" from the Yashica if you decide you like using a rangefinder, but, that would be up to you. Maybe, a model with an interchangable lens would be a nice choice if you decide to replace the GSN.
