Very Expensive vintage chip

Call me crazy, but aren’t ICs supposed to be cheap? Not these extremely Rare Silicon Systems SSI-263P chips. They are analog “phoneme generator” used in Text-To-Speech (TTS) Synthesizers. This chip is up to $50, but that may be cheap, considering this identical auction for what appears to be the same ic closed at $142 and still did not meet the Reserve! Speech boxes pop up on eBay once in a while and usually are pretty cheap. However for those who can’t wait, order a SpeakJet for only $21.99 from while there, also check out the video generator IC looks useful.
