Hi John. Do you have any idea why they closed your Why nobody likes Pentax thread? By the time I wrote a suggestive reply it was closed and could not post it.
JohnB is a great guy - I barely knew him and he went out of his way to help me verify if my sensor is ok (even set up an FTP connection for me to send RAWs!). People like him are rare these days, and the forums are very lucky to have him on board! I'd buy him a drink if i knew him in person.
