Welcome to APUG. It's good to have you here. If you should find yourself in need of answers to film-related questions, there is probably no better place online to find them than APUG. The volume of film-based expertise available is truly staggering and those who have it are always very willing to share. Please don't hesitate to ask. Hopefully your wife is correct.
The Canonet QL17 is a wonderful little 35mm rangefinder. I own one myself. I purchased it from a fellow member here for a very fair price. It has become my favorite 35mm carry-around camera.
