I use a 2100; had used a 2000, 740, 640, 630 .... kept upgrading as Yamaha kept introducing upgrades, and I WILL upgrade to the 3000, because:

ease of use, light to carry, good sound if you know to use it, can get used to the key feel if you want to ( If I was too finiky I would never progress !!), good styles and voices; Over all a Good Arranger Vs cost Vs Other available options !!
