Most people seem to like the sport wheel over the regular one.
I do not know specifically for the 987, but I am sure that a wheel swap is possible. Depending on whether or not you need a different airbag too, you are probably looking at close to $500 (w/o airbag) or $1000 (w/ airbag), maybe less if you look on eBay.
I would give Sunset Imports a call and talk to them, they will let you know what you need, and they have the best prices for Porsche parts.
