I have the Acer set and they are very nice. I ran a set of Acers in my Evo3 when I had it. Very smooth. Very nice bearings. Great customer service too. Answered my questions in a very fast and timely manner. And even helped me out when the SD bearing kits were not finished yet. Ask for some pics of the Acer chick. They'll send them to ya hehe... 
Acer is top notch, the carbide diff balls and battery braid I got from them are excellent.
