After many years of desire I purchased an MX from a local dealer last year, with /f1.7 lens for 59. The meter doesn't always work but I carry the Sekonic L208 and it's still a compact package. I quickly added a 28mm and 35mm lens for very little money. A 135mm was purchased from a charity shop but hasn't been used yet.

I used to be a fan of Canon FD equipment but my remaining Canon bodies (FX and FTBn) are giants in comparison with the MX and I don't have a practical reason to choose them over the Pentax.
