pretty much any parts place will carry multiple brands of white skis
as andrew3399 said, SLP Powder Pros are pretty good
the stock gripper skis are some of the BEST OEM skis, but if your after a different look the SLP's can be had CHEAP!
gobigparts.com has the FULL Pro Kit (skis, saddles, loops and carbides) for $305 ALL IN, plus a bit of shipping
my local guys couldnt match it or come close to that price
lots of guys have good reports on the performace of them too
I too put white ones on my 2012 Pro and love they way they look
super easy and clean install
have run C & A's prior and never will again, as they are a 4 man job to install them
