OP, take note of the above. There are quite a few members looking to buy bitcoin with PayPal, including myself--but I'm done buying for now, so I'm not making an offer here. It's important to note what BitMaxz said, that you shouldn't necessarily trust high-ranked members or those with green trust, since accounts are frequently sold and even legitimate members have been known to scam for even small amounts. PayPal isn't the best way to buy bitcoin unfortunately, but you might find someone who's willing to deal with you honestly. Just be careful.
Virwox is also another option but I don't know if you can exchange your BTC fast.
I've looked at their site before, but that was a while ago and I recall not being impressed by them. I'd much rather deal with members here than take my chances with a site like that and pay higher costs than I need to. Usually you can do 1:1 trades based on the preev rate, and it's hard to beat that.
