selling complete operating tank; any ideas on prices to ask?

[Blom]

I had a 90g with a 45g breeder as a sump. A 50g plastic drum for RO/DI water. Custom stand, a mid stream skimmer, Aqua Jr Controller, Auto Top off, and a 4 ft 8 bulb tek T5 light. With live rock and what not I spent close to 5500 bucks. Sold it all for a little over 1600. Great hobby to get into on used stuff, but no resale on things bought new (for the most part). Im guessing you would be lucky to get out of that with 750 in your pocket.
