I think only VirWox that I know you can buy bitcoin with PayPal but the problem the fee is high.
I'm about to suggest this because I've used it before and you are right, the problem is the fee is very much high compare to the P2P deal that you can transact with those reputable exchangers here in the forum.
but I did it once a year ago at Virwox. It was good but too bad the site removed the paypal options last January IIRC.
Oh my, so there's no more option for SLL/BTC on Virwox, I guess the best choice that OP can do is to choose from the suggestions above from reputable and established exchangers of PP to BTC in the Currency Exchange.
