I wonder is it worth it ?? I use the Big Piano Sgid and it is full size and Brilliant but if I play it hooked up ie if I use for example an X1 to drive it, it sounds better than the piano in x1 but it is alot less quality than when played direct. So I am wondering if you could get an old either full size corg sgid or the smaller corg =same number keys as an arranger and use it with your Ps 2000 ie play two keyboards.=Right hand on piano and left on arranger. It is a lovely combination. Old corg pianos about 10 years old are fantastic. Pierce in Ireland
