I'd be curious to hear what people's opinions of xe.com are. My questions are if it is worth doing? Was there a fee that I cannot seem to find listed there? Do they have a minimum?
I use xe and I really like it. I've got a US-based employer that pays me into a US bank account, and I use xe to move the money to my UK bank account. Xe debits my account in the US and does an ACH/EFT payment to my account in the UK, so there are no fees from either bank. The only fee is in the exchange rate, which winds up being less than a wire transfer fee would be. I haven't used Paypal for this, so I don't know what their fees are.
I've transferred as little as $200, but I don't think there's a minimum. There's a maximum, but all you have to do is call them to get it raised. The only down side is it usually takes about a week from the time I place an exchange to the time it's in my account in the UK. The money comes out of my US account pretty fast, but it takes 4 or 5 business days to clear into my UK account. I think this is pretty much the case no matter what method you use to move money, though.
Hope that helps.
