I bought my 1st SX-240 in 2012 for $500.
It broke down within a year after the screen began to freeze and scramble.
Very shortly after that I bought another SX-240 for roughly the same price which lasted me from 2013-2016. I HIGHLY suggest you get the battery changed at all cost! As these synths can be very problematic with battery leakage.

Sometimes people like to compare the SX-240 to a Juno 60 or Prophets. It is not in that league sound wise! The Prophets and Juno's just sound much nicer to me.

SX-240 is NOT good at bass. Envelopes too slow. It is better for pads or complex combinations of two sounds. But you can also do this with an ESQ-1 at 25% the price and have a much nicer sequencer on the Ensoniq.
I also purchased a SX-210 in 2015 for $350 at Trade Up music here in Portland Oregon. It was also very glitchy and had far worse sounds than the SX-240. I would consider the SX-240 to be only slightly better than a Korg DW-8000. An Ensoniq ESQ-1 and a Juno 1 ( which is the best value right now) It is not as good or not nearly as nice sounding as a Juno 60. Juno 106. Korg Polysix or Prophet 600 / 5. And to compare it to a Jupiter 8 is very insulting and almost laughable. As far as modern synths go. It is almost as nice a Deepmind 6 or 12 but not nearly as reliable so make sure budget at least $1000 for repairs if you intend to keep it for over 5 years.
