I often see used BS2’s go for quite cheap here in the US.
I love my BS2; it was the first synth I bought–if we ignore the DX100 I bought as a teenager that convinced me I was just too stupid to understand synthesis for a decade–and I still have it (and use it, for a bunch of things, actually; you may not use the keyboard that often, but if you find yourself in need of a controller, it’s polyphonic, with velocity and aftertouch and has a nice action, in my opinion–it’s my go-to for laying down a quick melody or a handful of chords, provided they fit the range–and the arpeggiator, while not deeply programmable does offer a lot of useful varieties).
