There are 3 different versions of that wheel also which will determine the actual deal your getting.
I purchased my set brand new for $460 shipped, they are the CF1R's singlebead lock front and rears. The Tech3's are their strongest most expensive wheel.
Quite honestly in my opinion, if your just riding sand these wheels are a little overkill unless its just the look your going after
They are just a tad heavier than an aluminum wheel..
