ED,I got the radio without any knobs. I thimk this is something people robbed off the cars it seems. yes ,if you get a cd player with an fm tuner in it you can listen to fm radio also. The main thing is to get a player with good anti skip protection. As for price I feel the one I have on Ebay is a very good deal. I would only consider a trade 2 for 1 if the One I keep is in good cosmetic condition and would prefer a photo of it. I did one of these deals before and what I got was a radio that was so poor cosmeticly that is was only good for parts. Now understand that this is not stereo but the left and right channels are connected together so you get a full sound. You also get to keep your 6 volt radio and listen to your favorite music on cd's. It beat the heck out the boombox on the seat or a 12 volt battery in the trunk to run a modern radio. I have this set up in my 49 Desoto and I love it. If you or anyone needs a radio rebiult feel free to email or call 9am-9pm est. Thank You Bob
