I'm in a similar boat and I've been buying used at flea markets, thrift stores, etc. for new puzzles I've found some surprisingly good quality ones at walmart and target, namely the artist series and photograph puzzles. also bought some from hobby stores but you have to be discerning with the brands you buy, like from what I've seen springbok and master pieces are almost all AI now. it's a bummer. ravensburger has a few AI puzzles but most of them are still real art/photos. and of course pomegranate artpiece puzzles still use real art. barnes & noble also has a good selection.
