I totally forgot about the
Roland RD 300 SX
It's like the baby bro to the rd700 sx, maybe it's ok, although some people at the piano boards are dissing it for some reason. In DK the price of that is around 1300 Euros, but could easily be cheaper elsewhere.
I looked up Yamaha's stage pianos; their p- and cp-series look ok, and their S90ES looks
sponge worthy, though pricey.
From Korg there's the TR 76 Workstation with 76 keys (comes with 88 keys too, then it's called TR 88) at a reasonable price. They also have the
SP 500 but I haven't seen that anywhere yet.
I hope it helped, duderino!
