well, if you want a real sounding piano, I've heard good things about alicia's keys... but the sample you provided doesn't sound like a "real piano", it sounds like a "90's sampler" piano, in which case you should probably look for some korg m1 samples. The m1 was hugely popular (i think it was the best selling keyboard of all time until the microkorg) and it was all over 90's house/techno/garage records. theres even have a vst version of it for around $50:
