I love PayPal, one of my other hobbies is watch collecting, I have over 700 transactions on eBay, 95% watches, and probably another 100 plus on watch forums, I bought and sold watches from $100 to $10,000 with every transaction going through PayPal with never an issue and I do not use "gift" or "Friends and Family" unless I'm dealing directly with a friend.
I would expect to pay the 3% fee and on anything I sell just as if I was taking a credit card payment and had to pay their fee, yes PP's fee is a little higher but you get much more protection then a straight CC transaction.
I'm guessing that the reason they are holding the $1,000 for 30 days is you are not a verified account, after a certain number of transactions that will not happen.....I get 4 figure payments all the time, immediately transfer to my credit union checking account and the money is deposited within 4 or 5 hours
