Multi-software powered 888 casino and 32Red are two well-established and safe online casinos that accept PayPal deposits and withdrawals. They also charge no fees for money transactions with this e-wallet.
If you want to start playing at 32Red, you will have to dish out at least $/€/£10 per transaction. The 888 policy is slightly different: $20/€15/£20 is the minimum deposit requirement. Deposits at both venues are almost instant.
