I've never had a problem with Paypal. I rather like using it, but it does take a few days to transfer funds to the checking account. That seems like an anomaly in this day of electronic transfer!
The real problem I have with Paypal is the MSP's use of it. They rarely put the shop date, shop number, or other reference information in their little information comment. Matching up the payment with a shop (or several when they batch them together with one payment) is a pain in the neck. I'm automated heavily here, and it really pains me to go searching for jobs and trying to match up payments with completed shops.
I like the fact that if I pay for something on Paypal and I don't have enough funds in there to cover the amount they automatically transfer funds from my checking account to Paypal to cover it.
