You wont find anybody offering PP and if you do its a scam.
Your best bet is btc-e.com with credit card over Netteller.
Although you might wanna check the fees before you commit.
This is not the case with ALL of the forum sellers, I have bought from people that accept paypal and have sold to people that sent me paypal payments.
The reason why people avoid paypal is because of its high transaction charges and the insecurity of it's reversibility.
Btc-e is best used with liqpay /interkassa, but using neteller with btc-e is quite complicated, the minimum amount to be deposited is atleast $500 and you have to create a support ticket to start the transaction, plus neteller and btc-e have their own charges. Especially withdrawing cash from btc-e is very expensive, compared to other exchanges.
The only other exchange that overcharges MORE than btc-e is Virwox.
