Hi, I live in Montreal, where Osaka is located, I shopped around when I bought my RB25 and although Osaka has good prices, there product is crap.
When you see there products on let's say e-bay, take a good look and you'll see that it's always the same pic. for a given engine and this is probably the best one they ever had and they kept the picture to reel in some, too far away to complain, fishes.
