I understand your feedback concern and it's a sticky item with powersellers because as a seller we are NOT allowed to leave anything but positive, thats why sellers such as myself typically wait until you the BUYER leaves feedback showing that you got the item and the transaction is satisfactory.

eBay needs to fix this problem because why would i leave feedback first (which is nonchangeable) not knowing what the buyer thinks and then get slammed with a nuetral or negative which in turn with the new DSRs will actually cost real money in eBay fees!
