No, I don't.
They already have 7 days to pay for an item and then to have to wait an additional 10 or more days for a check to 'hopefully' clear is way too long for me. I had a buyer request to pay with a check one time. She was a long time eBayer with steller feedback. I accepted her check and all was well. Otherwise, I prefer not to accept them. USPS money orders work better for me if a buyer doesn't want to use PP or pay with a CC.
