Squeak dont you get it?.....it doesn't matter many people don't even know what an arranger Kb is...all they see is keys....it could be a Casio $199.00 unit or it could be a Nord synth in their eyes "Oh that's nice my grandson has one like that" Yea right!.....the prices they charge for these units are what the market dictates whether you think it's worth it or not they are selling like crazy. It's all about making money.
