Pricing advice
 

Does anybody have any advice on how to price used equipment? I have an aquarium I would like to sell and I've put in a significant amount of money (about $7,000 in hardware). It's 2 years old and in good condition. How much should I sell it for?

It depends on the quality,brand name,if your willing to sit on for awhile

You will always get more selling it in parts too. It would be rare someone will want exactly everything you have. But, as a system, 7k new might get you 2k used. Give or take 800.
