I'm going to propose a completely different idea to you. If you want to go manual, why don't you look for a decent used Pentax LX? I would say they are (were) Pentax' top of the line professional camera at one point and I am sure you can get a used one on KEH, etc... for a pretty good price.

The advantage besides having a top quality camera is the possible accessories you could get, albeit in the used arena.

Just a thought.
