A few days before Christmas I stumbled across a chrome Pentax SL body on eBay for $ 8.40 plus $15.00 shipping from Japan total of $23.40 (eBay item # 123540212897). Even though I already have two SL bodies I bought it.
The finder was filthy, had some fungus in it and a murky black horizontal line through it when you looked through it. Otherwise it was clean. I figured if the finder couldn't be fixed I'd still have a cheap parts body.
The body arrived promptly and I was happy with it. Re-packed it and sent it to Eric for a CLA. Eric replaced the prism, replaced the seals, and serviced the shutter. Total cost including shiping shipping was $107. It cost me $12 to mail it to Eric so total cost came to $142.40. Not bad at all.
That may seem high but it is in like new shape & will last me for at least 10 years so I'm happy and I save one from the trash bin. The SL has no light meter and is a pure mechanical camera.
I now have 3 SL bodies.
The black one I bought out of a pawn shop in Texas way back in 1978. Its had hundreds of rolls of film through it. It sports a Nikon P Apollo screen, Leica screw-over cable release, Pentax LX lower strap lugs, and Ritz Camera "Ruggedized" skin covering. While I was on active duty it took a 200 foot fall in a rucksack that broke free during a parachute jump. Didn't bother it in the least.
The Pentax SL is my favorite m42 body. I am planning on putting another Nikon P screen in it.
