Question Reliable used motherboards

Is Ebay a reliable source for working used motherboards and how can you be sure that they will work?
There are all kinds of sellers on Ebay, from honest to outright cheats. Even with brand new components there's possibility to get an DOA component and until tried and checked you can not be sure. Just look at sellers reputation, eventual warranty and possibility for reimbursement.
 
Personally speaking the only used motherboard I've bought was from a Newegg seller who had a really good return policy. Buying used anything is always a gamble so you want to make sure that you're covered unless you plan on writing off whatever money you spend should things not work.

Pretty much any motherboard which works with these CPUs should be perfectly fine.
