Yes, Pianoteq is great, and I've purchased the pro version, which I've found to be well worth the price. When I got Pianoteq I thought the at least now I found the best piano I will ever need, and stopped considering others (and still feel this way). However I received Piano V free with my Keylab 88 mkii and have found it pretty impressive. Not yet up to Pianoteq, for sure, but I really like to think there is some competition for Pianoteq in the modeled piano market. I specifically miss the aftertouch support in Pianoteq (I don't think it's possible in Piano V to map aftertouch but maybe I just haven't figured it out) and the ability in Pianoteq pro to modify each key. While this sounds like a pain, they make it easy where you can draw a line across the keyboard showing which keys should respond to velocity, aftertouch, etc. in which ways. The Keylab 88 does not have a graded action, but by drawing a line that goes up and down at the ends you can simulate a graded action, in Pianoteq.
