This, or the Nikon FE or the Canon AT-1.
Not that I said the Canon AT-1 and not the AE-1- which have way more electronics and are prone to electrical issues now that they are 40 some-odd years old - The AT-1 doesn't have auto exposure or shutter speed priority. so less electronics, more manual, better for beginners. It retains the very accurate light meter from the AE-1 and exactly the same layout and feel.
The Nikon FE is absolutely fucking fantastic. Even though it has some electronics in them, they are made extremely well and are stupidly robust. They have a super accurate light meter - more accurate than the K1000/AE-1 and are possibly more accurate than most people's ability to use it properly.. It just fucking works great. The battery life is so long you forget about it (My brother gets about 4 years or something out of his - so it's not like you need to worry much about it...) It also works well in cold weather. I've taken my brother's out in like 20 degree snow days and it works awesome. It has a great viewfinder that shows you all you'll need and is crystal clear. Lastly, the thing uses all lenses from nikkor dating back to 1959 - so you have an insane amount of lenses of very high quality that you can use.
Ultimately, if you can find an FE for around 30-40 bucks, absolutely jump on it, because even though it IS more electronic AND more advanced than the Pentax K-1000, you can get a little more use out of it - not to mention, you'll save film very well - as it has silly good film economy, meaning just about every single shot that you take will have absolutely perfect exposure - unlike a lot of newer cameras that won't wind correctly - even the K1000 can be a little finicky as it's not the most accurate in this regard.
