Any photographers here?

I was at a local pawn shop this past Tuesday looking for a 35mm film SLR. I've been thinking about getting into photography, and wanted to start with film. Anyway, when I told the guy what I was looking for, he just held up one finger, said "Wait right here!" and walked off. A couple minutes later he came back with a big leather case.

I put a 12oz. Red Bull can next to the box for size comparison.

When he opened the box and started pulling cameras out, I wasn't expecting what I saw.

These were the first three he pulled out. A Pentax K1000, a Yashica Flash-O-Set, and a Pentax P30t.

Also in the box were a bunch of extras, including some flash assemblies, a few close-up lenses, a light meter, and a filter.

But the last camera he pulled out actually made my jaw drop. It's a Mamiya C330f Professional from the late 70s.

This is a professional-level portraiture camera. It is a medium-format Twin-Lens Reflex (TLR) instead of the more familiar Single-Lens Reflex (SLR) camera.

It shoots either 120 or 220 film, or single photo sheets with a different back.

When I asked the guy at the pawn shop how much he wanted for everything, he said that they had been taking up room for so long in the back that he would be happy if someone offered him $50 for the lot. That was a steal, cause the Mamiya goes for anywhere between 3 and 4 times that by itself! Needless to say, I bought it all. Now, I just have to learn photography. Anybody have any pointers?
