Just thought that you might be interested in this eBay shop: http://www.stores.eb....uk/id=36214385
They've got USB sync and charge cables for SPV plus the in-car USB power adaptor for just £14.99 + £2 postage.
I've ordered one this afternoon and will update you about it worthiness and the quality of delivery from the seller when it arrives.
UPDATE (27th January 2003): Cable arrived on either Friday or Saturday (I was away so not sure when exactly!) and so far, works fine with both sync and charge!
I've read some reports stating that the charge function doesn't work because USB is only rated to 500mA - currently charging with just 64mA being reported used, so the excess must just be for surges in activity. But I guess that it may also depend on your PC......
Anyways, works for me and the supplier is prompt - what more can I say??? Does exactly what it says on the tin
Not tried car USB adapter for charging via the cable, but I hope that should be a lot less to worry about.....
