EXS 24 Logic Sampler Users Group

Hi Gang,
OK, I'm getting repetitive of my tired old piano samples. I've overused 
the EXS's Yamaha Grand, which is a great patch IMHO.
Also Old (and somewhat Tinny) is my Prosonus Steinway Grand (AKAI disk)
What other great samples are out there that you guys would recommend 
for me to look into to spruce up my Piano library?
I realize that a piano is a piano, but some different samples help the 
palate of colours.
Thanks y'all
Ciao
