Buy from eBay... there's where I got my Praktica MTL3. Sturdy, solid body, but the meter doesn't really work ( I use a handheld one, or otherwise guess my exposure.) M42 mount has great lenses, especially the Pentax SMC Takumars... superb build quality. They can also take Pentacon6 lenses meant for medium format -- that means you can use legendary lenses like the 180mm Carl Zeiss Sonnar, etc. Lenses in M42 mount definitely cheaper than modern AF lenses; and afaik they don't lose out in quality for the most part.
