Nice thread.

For me, the need to upgrade is slowly diminishing with each change I've made. It was even a push for me to change from T3 to T4, and now that I have, the T4 has everything I want and beyond, I can't see myself changing my TOTL model in a hurry. It sounds wonderful and I can't fault it, so if there were no more arrangers available it wouldn't really bother me too much for this line.

The S950 however is almost perfect but I just wished it had better choirs and vocals, I am pretty sure the next S model will have these and that would probably be the only upgrade I'd need in that range (unless Yamaha release a choir pack for the S950).

We are lucky to have such fantastic instruments and you can't really go wrong whichever keyboard you buy.
