I just bough a 250 acrylic tank for 100.00 and a just seen a thread at our local site for count it 3 55's BRAND new still with all the tags and card board for 50.00 each..
Plus my 150 cost me 300.00 with tank stand light ... and Glass tops.. Filter was also 25.00.. So youare telling the WRONG people no way.. I just sold a 75 about a month ago every thing included for 200.00.. and a 90 for 200.00 with EVERYTHING..
Plus i added everything up used as his tank IS NOT NEW... NEW Is considered from the store

Used is even in the wrapper but not form the store.. There for you lose value kind of like a car... You drive it off the lot and you lose value..
I was not dissing anyone.. I was just pointing out the facts of MY EXPERIENCE which seems i have a little bit of to be able to do what YOU think is impossible.. I also stated that he could very easily get 250.00 out of it if he was patient..
But I assure you, I could pick up all that stuff in the same condition for at very least 50.00 less. As could Wyldfya

Once you are in and around buying and selling tanks a little, you can easily get what you want out of them or get what you want NEW, for much less than at the store..
I feel bad that you are unable to find these kinds of deals. But I ASSURE YOU they do happen everyday everywhere

Patience is the key to both Finding and Dropping tanks
I did not insult anyone or deny he couldn't get what he wanted.. So please understand my view.. I have right now a 110 gallon I bought with everything for 130.00 WITH EVERYTHING

I could easily get 3 times that out of it inside of 2 weeks.. though I know the real worth .. And what I would pay for such a set up..
He has a nice tank and is asking a fair non hobbiest price in my
opinion 
As for the experienced Hobbiest that find these tanks EVERYWHERE.. They will not pay that. And that has nothing to do with this set up.. Or dissing it. he asked for suggestions and answers and he was given very detailed ones at that.. A USED TANK ...
It is common knowledge that a used tank price is generally and I say that loosely.. Generally half of what you paid .. Sad thing is even if you bought it yesterday...
To add to it he could easily get what he's asking

They are posted for 200.-250.00 all the time too.. It just isn't people like me that buy those

and if I do the price drops drastically beofre I even get close to going to pick it up..
