Why the arius? With your budget, a liitle luck and not fussy about used equipment, you can get a decent and good condition clavinova with GH3, 3 level sampling, amplification system. Perhaps check out the CLP240 on sale at the classified section here. Have patience to look around. BTW, if you are interested in a P120, let me know. I'm considering to sell mine. PM me if you are interested.
