I have a Alesis Ion in excellent condition and working 100%, just some small marks on the front below te keybed from were it has been sat on a A frame stand, barely noticable though.
Open to trade offers but the following are what I would trade for without a doubt as long as condition was excellent...
Waldorf Blofeld KB
Dave Smith Mopho KB
Dave Smith Mono evolver KB
Moog Little Phatty
Cash can be added/deducted depending on the trade obviously.
I am in the north of England and drive so can meet anywhere in the north to make the trade
