The Yamaha AN1x Synthesizer mailing list

Hi.  Currently using an Sw1000xg on my PC.  I've thought about getting the
AN upgrade board, it's definitely the dance sound I'm looking for.  However,
I've just come across a good second-hand AN1x which may be an alternative,
incorporating an upgrade for my small midi keyboard.  Any thoughts?
Good/bad idea, alternatives, pros & cons?  Also what's a good price for a
2nd hand AN1x?  Cheers!
