...but off the top of my head I would say that $500 for a 30 year old camera and a couple of lenses is no bargain. I assume the camera will need service, and possibly parts - got a person who can help you with all that? Ask that person whether this is a good price.
No. No no no no no no no. No. And did I mention no?
Film equipment prices are way down. You can get a lot more for $300 now. As Iron mentioned, what you are looking at there is the camera (and why does he say the year but not which model?) and two lenses. These can easily be found for $100 or less. Everything else there is cheap re-branded stuff that you will find people giving away all over eBay. And including a "Magna-lite model 100"? Seems like the guy is just trying to clear his house.
