No personal experience really, but if the turntable is still on order I'd wait a little.
Maybe it's fine the way it is, there might be some subtle differences in sound quality between different platters, but if the stock one is level it should be fine. 
Thinking of upgrading before you even receive your turntable is a very slippery slope, before you know it you're buying component A while you allready know you are going to save (a lot) of money to replace it with component B, your soundtrack albums will be banned to the attic and will replaced with a handful of Patricia Barber and Diana Krall albums, and you will start salivating over 500$ gold fuses for your fuse-box
