Hi,
If you're on a budget and like 76 keys, you might try out the PSR EW410. It has 76 keys and the Sweet! Pan Flute voice that you like so much. It is so inexpensive that you might consider the EW410 as a second keyboard besides a S975 or a Genos.
You might be lucky and get its predecessor, the EW400, at a bargain price (it is now discontinued, but the odd specimen might still be hiding in the backroom of some obscure music shop), which has practically all the sounds, styles and features of the EW410.
Regards,
Vinciane
