I just use PayPal as more people use this due to ebay. At the moment i get 2 sometimes 3 customers pay me through this £10 costs approx 30p and you need to get to £50 before transfer to your own bank account is free. Usally takes 7 days for it to transfer as well.
Look at it as another way for your customers to pay you. More ways they have the better its going to be.
