Thanx for the info....no surprise about NO 76 key model coming next from Yammy re: arrangers....
The 3100 or what ever they call it will most likely be a less featured "mini me" of the T2 IMO.
SD-1 is another animal in a good way compared to the T2.....try to check one out & do a search here on the SZ its been discussed many many times.

Good luck
