Just had a quick peek at the Flea3 site...the 76FPS 1/2" Sony 414ICX chip model would be the one to get, but at the current exchange rate and GST (sans custom payments and shipping), you're looking at $1110 buying directly from the manufacturer. Although shipping on a camera that weighs 58g would probably amount to $1. You'd pay more for the parcel they put it in!!!. Here, go and have a look...
