Need help on pricing for tunze 6025s

[nietzsche]

im breaking down my tank and trading it for a larger tank, only thing is hes not giving me much credit.. so im keeping some important things like powerheads, iwaki pump, sump, protein skimmer.
i have 3 tunze 6025s that are modified to push 1,200+ gph, you can buy the housing for like 5 bucks from tunze. theyre pretty brand new, especially one of them that i just purchased about a week ago. i asked if he wanted to buy them but only wants to give me 10 dollars for each one
if i sell them online what is a realistic price to ask for each one? 30-40 bucks?

I would venture to say if you were happy with 30 - 40 for them, that would be a good place to start. They sell for 69 I think on Marine Depot so half (especially considering the one is a week old) is a good deal and should move quick I would think. That's just my .02 worth. Your mileage may vary

My consultation fees, luckily, are payable in Tunze 6025's
