I had a Mettle 600AD with a battery pack I bought from Amazon for roughly $350. it was a great light, and I was able to sync it at up to 1/8000th sec using cactus V5s at the time. the only reason I really sold it off was because of its size. Compared to an Alien Bee the Mettle strobe was a behemoth. if you can get past its size, it's a great value.
Any examples you care to post using high sync speeds?
