Thanks for all the info, red.
Ive been looking mostly at Facebook in the community for sale areas (I know, caveat emptor). Right now I'm just keeping my eyes open for what's out there. My daughter has a nice canon, one of the multitude of Eos cameras available, and I've enjoyed using it. There are a surprising amount of them for sale on Facebook but they're still higher than I want to pay. There are the occasional Nikons that show up, too. Do t recall seeing many Olympus or Sony cameras yet.
I'm not ready to buy but wanted to start getting some info. Appreciate your help.
