I've bought 9 Turnigy's from them, from 1600 2C 3S to 5000mah 30C 4S and they've been well worth the money given the performance. I plan on buying more from them when I need them.

Try to find the ones you want in the USA warehouse (near Seattle), they are a little more, but the S&H is much less and you'll get them much quicker.
