1. The price was reasonable, quality styles and sounds, easy to use operating system, ability to change sounds and styles quickly for live use, also nice and portable and it's the first 61 note arranger I have ever purchased (prefer 76 but 61 is no major loss)

2. No, never had a Yamaha since the old V50 except for organs suych as HX1 and EL70

3. Didn't really go from another brand as still got Roland, had a Ketron SD1 and still own Yamaha and Kurzweil synths plus PC based synths/samplers.

4. Fast changing of sounds and styles which is a must for a live performer, OTS & registration features were a great benefit, hard drive recording and ability to edit sounds and styles to customise the arranger makes life easier.

Hope that helps
