I do have Alicia's Keys but I honestly never use it anymore. If that sound is what you're looking for, then fine. And it might indeed be the right sound in certain situations. But if you're looking for a more natural sounding grand piano, I think there are better options.
If so, I would suggest that you have a look at VI Labs True Keys Pianos (not to be confused with 4Front Technologies TruePianos which you've already mentioned). It's a bundle actually on sale right know (see this
thread in the Deals forum). You will for another week get three beautifully sampled instruments (a Steinway D, a Fazioli F308 and a small Bechstein) for the price of one Alicia's Keys.
You could also have a look at Addictive Keys
Studio Grand from XLN Audio, which is also a beautifully sounding Steinway D for even less money. It's one of my favorites. And XLN Audio normally have a 50% discount once or twice a year.
