My sister in law is in the process of packing up her house to move, and they found her husbands cameras from his college art classes years ago. This K1000 seems like it works, but is in serious need of a CLA. But the mirror is stuck in the up position. I can push it down with my finger and it stays down, but if you trip the shutter it stays up. My question is... is this a relatively inexpensive fix? I've long wanted a K1000 and almost bought on off the bay. Are they pretty easy and cheap to restore to operating status?
