I spent $1500 a couple of years ago on a nearly complete set of NP magazines from eBay, all in good or better condition, with posters, trading cards, etc.

Some of the best money I ever spent. It’s amazing sitting down and having my childhood right there with me again, and there’s nothing like having the actual magazine and not just a pdf. Invest in a set + a real console and crt tv, and it’s the closest you can come to feeling like a kid again.
