From his comments ("B3", "get back to live playing", "pedals", etc), I would say he was looking for the ORGAN experience, not a keyboard with some organ patches on it (no matter how good).

  Chas, you hit the nail on the head. I do miss playing "for real"
and my fondest memories takes me back to early eighties 
playing a Hammond X5 with  small Italian rotary speaker and
pedals coming through a small bass amp. Right now I'm reeking
with nostalgia and I'd love to have an organ,  pedals the lot. 
I wont have to worry about a leslie speaker and probably wont 
make any money playing jazz standards, whereever. But for me 
music was not about money when fell in love with it 50+  years
 ago.
I will continue playing arranger for gigs/money and it's
 unlikely that I will upgrade to a Tyros 5 or the like.
Thanks all for the contributions..............now to get some
 money for that organ, where's my arranger !!!!!!!!!!!
