If I knew nothing about keyboards and wanted one, I would have to have a demo.

I'm not the greatest keyboard player. However I won't buy any keyboard from anyone because of a demostration.

I want one in my house for 30 or 40 days to try out the sequencer etc. In my town no saleman I've met yet knows very much about sequencing with any keyboard.

No demo is going to show me everything I want to know about a keyboard. I want the 30 40 day opportunity to use it myself in my home with my own hands. I know what I want and need not a salesman. Don't mean to offend anyone. That's just the way it is with me. Everyone is different.
