Well I didn't end up getting the MS10. It was a great one though. It was what they call a 'beauty item' - which means it didn't even have a finger print on it! It went for 28500yen. I was only prepared to go to 25000. To give you an idea of beauty item status - that CS10 I bought wasn't even close, but you would be hard pressed to find a mark on it.
MS20s fetch really high prices here at the moment.
The SH2 looks really good, but they mentioned something about a slow LFO that I can't understand fully. I'll get my wife translate later. She knows heaps about synths now, hehe.
