I grew up with an acoustic piano, and had a grand piano in my flat for 10 years. I bought the SL990 when I let the grand go - and I chose it because the recommendations at that time said that it was one of the best (for the price) for someone who wanted something similar to a real piano action.
I have been happy with it, and agree with the reviews from back then that it is really a good replacement. You can look at the Yamaha Avantgrand, which are better but also is 10 time the price of what I paid for the SL990. I have no intention of replacing it, and if it break down I might consider finding the same model again - but in other words, I have not been paying any attention to what has happened in that market segment.
One thing I will recommend is to get a DP10 or similar, and attach that to the volume input on the SL990, and then reconfigure PianoTeq to use CC7 as sustain pedal - then you will have the full feel of the pedal as on a real piano. Then you can use the sustain input for either a sostenuto or a soft pedal, to your taste (I chose sostenuto).
