If it is a random one, NP is the best place. The 10%-20% that other places charge does not give you higher sale to compensate.
If it is something special, then GD could be worth the shot. No way JYCB could have sold for $4K on NP. But again the risk is yours. Setting a high reserve might also deter buyers, so you risk selling for the same as on NP and then paying fees.
