Bryan and Tony,
I have the SD1 in my store in California. Many of my X1 customers have come in and played it for hours at a time. Not a single X1 owner wouldn't like to trade in their X1 or just have the SD1 as another keyboard. It has many new features and most of the X1 features. However, some players do not want 76 keys and would like to have speakers. The SD1 will sell for approx. $3200.00 in US dollars. Some dealers might be higher, I doubt if any will be lower, but this is great news for most, because it is really no more expensive than the X1 with a hard drive and a vocal harmonizer added and the SD1 already has these features standard.
