Yes, a good solution to limit potential damage (and it's actually a good idea for all online purchases) is to have a DEBIT CARD rather than a CREDIT CARD (or as Nova says, a credit card with a low limit), and make sure it's issued by a bank rather than GE or Woolworths or something like that. Check with your bank/card issuer to ensure it has similar protection to that of a credit card if you decide on a debit card.
Leave the account with a low balance - top up by account transfer just before you buy something - and the risks are somewhat minimised.
Remember that if you've not been refunded if a PayPal claim is resolved in your favour, you should go in person to your bank (asap) and initiate a chargeback. Once you explain the situation to your bank, they will start the process. Be aware that the merchant against whom your claim is will be PayPal, not the seller.
