I have recently seen the MS-20s for sale and the prices have averaged around $600 US. Also, I have seen one which was reportedly; "in absolute mint condition" for $950 US. There seems to be some interest in the MS-20s, as with all of the older and classic analogs, but due to the sky-rocketing prices, the frenzy is wearing down and people are turning to the new analogs such as Doepfer and Nord. If you are considering parting with your MS-20, I would recommend selling it now.
