Cassettes still rock!

I agree that cassettes can sound wonderful. I have a collection of 35  cassettes, recorded on a Nak 600 deck (which was stolen by our movers! They knew what to steal!). Currently, I have a (two heads) Marantz Deck, with an all-electronic control (touch switches), headphone output, Dolby B/C, and a very quiet, smooth transport. I got very excited about  cassettes in my youth, when my father bought me a Sony Walkman during a trip to Switzerland. I am talking some 30 years ago, yet Sony already employed SMD (Surface Mounted Devices - read Chips) and the overall build quality was superb. I remember listening to the (equally superb) headphones during entire nights! BTW, anybody here can tell me what a new, blank TDK SA90 BLACK Limited Edition cassette can fetch?  

I like the sound of cassettes as well. I have 30 of them, recorded on a Nak 500 deck (which was stolen by our movers! they knew what to steal :-). Right now, I am using a two-head Marantz deck with electronic control (touch buttons), headphone output, Dolby B/C, and a very quiet, smooth transport. My "affair" with cassettes began in my youth; at the age of 17, our family flew to Switzerland, and my father bought me (an expensive!) Sony Walkman. Mind you, this was 30 years ago, yet Sony used SMD's (Surface Mounted Devices - read Chips) and the build quality was exemplary. I remember listening to it (with equally superb headphones) for nights on end. BTW, I do not agree with some of the posters here about the quality of Denon's cassettes; mine had deteriorated badly over time. In my experience, TDK SA and That's cassettes are the best. BTW, anybody here can tell me what a new, unused TDK SA90 BLACK Limited Edition cassettes can fetch? I've got a few, maybe someone will be interested in buying them, but I don't know how much to ask for them.
