I'm selling a Tamron 17-50mm f/2.8 k-mount (pentax) that is in as new condition, boxed with all bits, unmarked. Has only been used to test it works - I returned the K5 ii that I bought it for and now have a load of other stuff so don't need it. Wanting 170 inc delivery as it's new - I paid 199.
It was bought from digitalrev as an import, but if you're buying second hand that doesn't really matter - I will, however, help you contact digitalrev with any warranty related problems if they come up as they have a local warranty, of which there is still about 11 months remaining.
I also have a Pentax-A 50mm f/1.7 manual lens pictures with the tamron below that I'd like to sell for £35 inc delivery - it is in stunning condition for the age and comes boxed!
