I haven't been planning to buy another old analog synth since I opened my Juno106's cover and found out how it was built and in how poor condition the internal cablings were. I know people who's synths just don't work anymore. Those analog synths are great but you never know when's the day that it won't start up anymore. Not a huge problem with some mono-synths without integrated circuitry but Juno's and others which use special LSI's cannot be repaired if the parts are not available anymore. I'm not sure if Roland still make those filter- & oscillator chips but last time when I asked that from Roland service, there were only a couple of them left in the world and no idea if there will be more or not.
