Quick, quick, quick. Which one of these 3 webcams?

[WriggleJiggle]

Help! I have to decide between these three webcams. Can you tell me which is best?

1. Logitech Quickcam E3500 £19.58
2. Microsoft Lifecam VX1000 £14.67
3. Creative Livecam Video IM Pro £14.69

To be used purely for video chatting with the grandparents. Not interested in it taking still photos (although I think all of them do).

Arrghhhh. Choices.

we've had 2 diff logitech ones and been happy with both.
tbh they're all much of a muchness I think
