I've had the Hayabusa for a couple of years now and they are awesome
Second here, I have 3 pairs actually (ha ha) and rotate them to spread out wear and tear. So far no problems, have protected my feet well (and prob helped with the ankle sprain I suffered in August from being worser than it ended up). You can prob find them on eBay from a wholesaler/retailer for a pretty good price (and it comes with a wash bag usually too).
