I’m on the fence about buying a new point & shoot camera for my upcoming trip to Ireland. My current camera does not have an optical zoom. The one I want is the G7 Mark II. It’s normally $699 but Canon has discounted it to $649 for the next few weeks. They also have refurbished ones on the Canon website for $499...worth it? I’m thinking yes, but need some reassurance. I’d like to save that $150+
