These are all over the place, thrifts, flea markets, yard sales and other places. At the local thrift they range from $2 to 1bout $8 depending on if am only, am-fm or include sw. I picked up a fairly nice Candle a few years ago that uses c cells and contains an ac power supply but I need to get a line cord or change the socket to something I can get a current cord for. It is am-fm-sw and has a leather exterior with chrome metal trim with only the very slightest pitting. Fairly heavy. However, the fidelity is typical portable and easily bested by my Grundig S350DL, a new version of the same format. However, with its plastic case and dials, it does not feel it would take the abuse of the Candle and survive long so to solve that I bought 2.
For a real keeper, there is of course the Zenith Trans-Oceanic 1000, 3000 and 7000 series SS radio and possibly the best of the best of the format. Not exactly cheap in realy good condition, they are well worth the price if you want an excellent portable.
