So I have just gotten into film the last few months. I have purchased k1000, me super, super program, a3000, and LX. Many of these were to acquire lenses or to test the camera out.
K1000 was built like a tank, but I wanted a better viewfinder. Also missing loads of things that make photos fun. Man the viewfinder was dark.
Me super I loved, but it was so close in viewfinder and size to the super program I kept the super program.
Super program I had Eric do a full CLA on, cost roughly $80 by the time you ship back and forth. I am keeping this one. Has everything a modern camera has except auto focus.
A3000 was horrible. The kids liked it best because it did a very noisy auto load
LX I just got and I haven't developed any film yet but so far it's the best pentax I have touched. Viewfinder is as good as the supers.
Good luck!
