I'd happily sell you 10, I just don't really trust the Paypal system. You being an anonymous person on the internet (no offence of course) and Paypal being the way they are, it's incredibly easy for the seller to get screwed.
Why not just buy from an exchange?
Yes of course exchange is a good way to buy bitcoins, if you don't want to use exchanger, I suggest using
BTCrow, bitcoin escrow Which protect both party in a transaction.
