Where Can I Find a "USB Cable I-USB33" for the Pentax Optio50 Digital Camera?

And It's Not on E-Bay's I've checked...

I've found one site where it is individually sold but they only ship to the UK. Im in the US.

Get in touch with Pentax Support, they should be able to provide you one or tell you where to find it... is it a very old model? Maybe it has been discontinued, then... However, note that USB cables are normally generic, you do not need to buy the same brand, you could use a third party... there are two types of USB connection: USB 1 and USB 2,
check which one your cam has, and you are ready to buy a generic one, as long as it plugs, it will transfer the data!

its on ebay :)
