My impeller is dinged up so I need to get a new one, but I'm not sure what to get.

I have an 04 GTX ltd supercharged with no modifications and I mostly wakeskate and wakeboard behind my ski. I basically want something that will be strong and cheap.

Should I get an OEM replacement impeller like this http://www.parkeryamaha.com/seadoooe...267000119.aspx for $220?

or

Should I get an aftermarket impeller like this Solas Concord 12/20 impeller here http://ad-discountperformance.com/in...roducts_id=299 for $230?

or

Are there any other props that you guys would recommend?

What are the pros and cons of different impeller options?

Thanks for the input.
