That's a good price, $10 shipping makes it $140.
However you still need to get the threaded adapter, either from Steve Mogg (
webcaddy) or Matt at
Telescopes-Astronomy.
Plus, an IR filter if you're planning to use it on Mars ($80-$120).
The ToUcam is $145 at Telescopes-Astronomy, so if you're planning to buy the adapter and IR filter fom there, it'll be cheaper to get the ToUcam from there as well, saves paying postage twice as you'll only be saving $5 in the end.
Still, not a bad price if you only need the webcam itself.
