Your PayPal balance is safe where it is. There's no need to move it anywhere.
But I would recommend applying for merchant rates to lower your fees. Depending on your volume, you can reduce your transaction fee to 2.2%, saving you $70 for every $10k you process. Google "PayPal Merchant Fees".
Yeah, I'm not sure why PP always gets the short end of the stick. What was the one the other day where the guy posted they had his authorization shut down for two weeks or something? There's always going to be horror stories and there's also always two sides of the story.
