Easier introduction to the classic DX series, the DX21 synth from 1980's in great condition with just a couple of touch up marks and two repro slider caps that are a slightly different colour. Fully working. 4 operator FM synth with layer, split and chorus built in. Pickup or post. £200
Personally - I would stick it in the loft for a few years - these will go up in value looking at slightly earlier keyboards that have gone thru the roof......
Your're right (just like pinballs at moment) but I've got so many now, I'm full to busting... hence this one is in the garage workshop taking up space. I also have a DX5 in the synth room so would rather sell it to someone that will use it I think . My loft is also quite full (not synths unfortunately).
