I think that the option to buy an expensive arranger should be left to the person buying the expensive arranger. I dropped $3483.00 for a Tyros 2, the T2 Speaker system and the Tyros soft case. I did it because I wanted to upgrade from my four year old PSR 9000. I am very happy with the purchase I made. I don't intend to buy another keyboard for another three or four years again. The cost is the cost. If its acceptable to me I'll buy it, if not...I wont!
Of course it expensive, but thats life.
I didn't start out buying the most expensive arranger. I have worked my way up to it. I have no problem spending the money on what I feel is a keyboard that I deserve to have.
