Does anyone have any good online/mail order sources for aluminum rims?

I really am interested in series 23 American Racing Wheels, but haven't found them in the right size,16x8, anywhere online. Does anyone have these rims on their truck? If so, I would like to see some pics. Also, since these rims are clearcoat, will they be easier to keep looking nice than a polished rim?

Thanks in advance for your responses!
