well if you will get all your investment in it back in the return, just return it and get the better stuff. If it is not perfect it will always bother you. It will bother you if your not completly content with it, and if it cost a lot of money. What you are experienceing is called congitive disonance (I'm a horrible speller). If you can get your money out of it locally, upgrade it.
Yeah people in Tucson seem to be fickle about tanks, they will get way into it, then just drop everything for a while and get back into it all over again.
I got a 125g set up on a mission stand and w/ canopy, coralife pc's, ehh skimmer, an oceanic sum, 150 to 200 lbs of liverock, and fully stocked (even a tang that is rare, i forget the name lol) for lke three or five hundred, i can't remember if it was three or five, but either way it was a steal.
