I have just bought a SD1 Plus - I intend to keep it having just given away my Yamaha US1 - I was told to buy the SD1 because I would run out of keys for the left hand buying a little Tyros - I am not certain the Ketron will hold it's price if I should decide to get rid of it - a bit like a big petrol car in the UK - the manual is a bit- heavy going - and there appear to be gaps that could be filled or is it just me.

Tyros 4/Pair SR 350/ PC with a i8 intel chip, XENYX 802, Ford Focus 2 litre/Tascam DR07/Brother printer/Designjet 500/ our Doris/5 Grandchildren/ white boxers short Kymart shipped over and Typhoo Tea Earl Grey
