Geeez, thats some heavy postage....how far do you stay from the shops?
The great god ebay, my friend. Cheapest webcam I could find in Oz was about $60 + postage. Mr Wong from Hong Kong sent me an el cheapo for the price mentioned. No fancy packaging a la Microsoft putting a single CD in a huge box and charging $700 for it, just a mini CD with barely comprehensible installation instructions, but the cam has been dropped on the floor at least three times and it still works. Good enough for me.
