Hello,
I guess it depends on the person and size tank. I bought my 240 gallon tank with stand, sump, (return pumps that I didn’t use), 5 wake makers I didn’t use, (went with different ones, tank was marineland tank was 6 months old (proof of purchase), and was 300 at my lfs. They have a 300 double deep with stand there now for 500, with sump. So just depends on what one is looking for. It was a great deal for me because it was an upgrade and was much much cheaper than a new tank and fairly new and has still no scratches in the glass.
If your trying to sell it etc I am not sure if it was a great deal but moving up to a better tank and didn’t break the bank then it’s a good deal. Not sure what you have now, but this hobby doesn’t have to be expensive if you shop and find good deals. They are definitely out there, like I see reef dynamic skimmers for super cheap, (and work), probably one of thee best skimmers in its time, and loudest but I see huge massive ones for 200 at times.
