In the past I've run the same auctions that John described but when sending the invoice I did not check the PayPal box but instead said that they had an
option of sending PayPal (no credit/debit cards) to my Personal PayPal account and then I providced the account name. If the buyer decides to use this option he must use the Send Money process within PayPal because there is no payment link within the eBay invoice. I haven't had any trouble and if the buyer accidentally tries to send a credit card payment you can easily decline it. Hope this helps.
