I know exactly how you feel. I am mainly a Nikon shooter, thanks to my dad. He handed me down his N2020, which I really enjoy. But, I recently bought a box full of Olympus stuff off of a lady who is trying to empty her house, because she's moving out of town. Turns out it had a Canon 50mm EF lens and a fairly recent Canon flash. Selling both has completely paid for this Olympus stuff, plus a little. I originally just planned to catalog it and use it to pay for a recent iteration of the Nikon 300mm f/4 lens, but it turns out that I got:
Olympus OM-1n, in great condition, functioning 100%
Zuiko 50mm f/1.4
Zuiko 100mm f/2.8
Zuiko 300mm f/4.5
I can't bring myself to put it on ebay yet! I don't want to get rid of it. In fact, I just bought 8 more rolls of film at Walgreens while I was getting a test roll developed. By the way, Walgreen's has Kodak Ultramax and Walgreen's house brand "Made in Japan" (a.k.a. Fuji, most likely Superia) both on sale, $8 for 4 rolls of 24-exposure film.
A quick shot I took, to make sure the camera works, don't remember the camera settings but it was using the built-in meter, 50mm lens, Fuji Superia 400 film. It was so great to see the negatives that the tech handed me; they were so nice and dark, full of data!
