I recently bought the SL 88 MKII GT. It has a very very nice keybed although a bit on the stiff side. For me personally I prefer be a bit lighter like a Nord Piano....although...having a price-difference of nearly 3000 euro.... I didn't get any escapement feel of the keybed. I find the keybed very precise; I hardly miss a key with this one while playing quick runs or doing strides.
Very very positive: just plug in an iPad with Pianoteq (running in AUM) and start playing. No extra devices and cables.
The only thing that I'm struggling with at the moment is the connection between key and sound. There's some latency involved and there is not much to tune with the onboard audiodevice which runs at max 48Khz. Sound-wise: it has a decent quality (more than enough for a live gig) but a Focusrite 4th gen for example is more clear.
