Got a lovely one of ebay for £255 the other day - great price. Just run my first film through it. the camera works perfectly and is a delight to use. It's also a piece of history. To think this was made in 1955 but works better and feels nicer to use than many modern cameras.
Here's my gallery of photos of the beauty, and photos from my first film taken with it. If you don't have one, and you get the chance, pick one up on ebay - keep an eye out for a good price. Some leica users now go made for a leica MP which might set you back a grand. it's based on this camera though, and with this one you will have an antique too.
