They reckon 10-14 days to sort it.
Have cancelled my Visa card just in case.
Bank have also said if we have any problems with PayPal, Visa will probably sort it - so not really worried about losing the money, just as to whether PayPal is as secure as they pretend it to be
They are secure but nothing is fullproof. I used them as a payment provder for a webstore I used to run and we got hit a few times, but everytime Paypal sorted it out, it just took time.
I wouldn't worry about using them to be honest.
