Absolutly. I held off buying the Empeg until a tuner was available that did FM AND AM. I know that you can plug in a walkman or use another deck but to me, those solutions are hacks and workarounds. If I didn't have a tuner, I'd pay lots...maybe $500 or more to get it. I've already got > $3000 in my stereo and it's not complete until I can listen to a news reprot or get traffic info.
I don't have any problem with people selling them on ebay at what ever price they can get. Thats just the way free enterprise works.
