This might sound contrary, and while it would be neat to see and play with them, I don't think that will tell you much or should be given much weight for a purchase decision. I would trust online reviews, forum research, etc, and settle on a machine that is in my price range and functions well over the course of years with good serviceability, with aesthetics a lesser consideration. Walking through a well-stocked store, even pulling shots on several of them will still give you an incomplete picture compared to thousands of users pooling their experiences online.
