Pentex or other M42 bodies are some of the best values on the market, although the meters are giving out, the range of lens is very impressive, many next to nothing in terms of price. The 1958 pre spotmatics are somewhat collectable, sounds like you got a good deal. Super Takaumar lens are multicoated and stand up aginst Nikon, but for value look for German, Vivtar, and Spritone lens.
