I picked up a small set a few days ago from a charity shop. It was 50 euro all together, which I feel was a fair deal, for both parties. Didn't realise the problems until I was on my way to the airport, wasn't going to haggle on price either way as it was a charity shop.
Anyhow, the spotimatic has a cracked prism inside

and the 50/1.4 has a slightly jammed focus throw (which will be easily fixed) however the real beauty is the 28mm, with case , and hood...
Pics below:
The Spot is in fine condition and works well, but the prism

The case's are in good condition
The 28mm 3.5 is immaculate, as new! and filter
The 50mm 1.4 Super-Tak is excellent but a little jammed. and pentax filter

p.s. I like submitting my own and reading others "buys"
