The top of the range pentax the pentax lx also the Suffers from many problems[/QUOTE]
With only a few expectations such as the Pentax K1000 manual focus SLRs are now 35years to 60 years old. The large manufactures such as Nikon, Canon, Minolta, Pentax, Konica all made decent reliable cameras, the top of the line bodies built for heavy use had better build quality, but many were used by professionals or advanced armatures and got the heavy use they were indented for. Your Pentax Super was mid level body, good features, overall reliable, but the electronic shutter is a problem, cannot be be easily repaired, lack of parts and trained technicians. So all manual Pentax KX, MX, Minolta 101 or 102, Canon Ftb, are all very good bodies, in your part of the world are there camera repair folks who work on bodies that are 35 to 40 years old? Where I live there is a photo shop that will clean, lube and adjust as long the camera is in good working order but will not take in a camera that might need parts. I tend to use my 90s mid level AF bodies, they are so cheap if one breaks I toss and get a new on. I do have have Minolta 9, but only use it when I out of town or shooting sports or wildlife, other wise I use Minolta 5s and 3s to avoid wear and tear on my 9.
