It's apparent here that one's arranger keyboard decision boils down to having to make 'tradeoffs' and figuring out what you're able to live with/without.

Determine 'your' highest priorities and work down the list. Everyone's priorities will of course differ:

1) Keyboard's Overall weight & size
2) 61, 76, or 88 notes
2) Key 'feel' and 'size'
3) Built in Speakers or NO built in Speakers
4) Sounds
5) Styles
6) Other 'must have' feature that 'you' specifically require

All above things considered, I still feel the Yamaha Tyros remains the best arranger to suit my current arranger playing needs. - Scott
