I was placing an order with EBuyer last week when I stumbled across an interesting USB cable for only £6.56. I decided it was cheap enough to take a risk on so I went ahead and ordered it.
I have now checked out the cable and can confirm that it is a PL-23XX cable. It works perfectly. It comes in generic packaging with a driver CD, EBuyer sell it as their own product. Their QuickFind Code for it is 39504.
The postage for the UK is as little as £1.87.
