I was lucky enough to find a "matching" set at different trips to Goodwill for my pots in red enamel with Teflon (not scratched!) interiors. The lids have strainers built in and they turtle inside each other. Nothing beats my Lodge skillet though. That is a must for camper or campfire and I'm sure you have one, Joe. Don't give it up. Just watch the size of your stove/oven and match that to you search for pots and pans. Of course, if you want to treat yourself, new is nice! I find the most important pot to have is a small Dutch oven for stovetop for making soup, boiling pasta water, etc. A couple of sauce pans heat up chili, beans, hot dogs, veggies, etc., if you are cooking inside due to weather conditions. We don't cook on an open fire but use a gas grill, so pots and pans still need to be small.

Other than pots and pans, the best thing for food prep and storage is disposable plastic containers with lids. Square fits in the fridge better than round, and they can be used a few times after washing before the lids won't fit anymore.

We just have a mix matched mess of skillets and pans that I have picked up here and there. They work fine but the DW would like to have a matching set. Maybe one day.
