Look at it this way. A stand should come free. Why do they need it? Not to mention you can build a nicer stand for less than 30$. Their probley florescent lights. You can buy them wall mart for dirt cheap.
buy a new tank and build a stand, you can build a canopy or buy a top. if you buy a used tank-210 and 240 gallons are close in size so I would think they would go for about the same price IMO.
well the 240 is saved for me for 400 on friday. the tank will be for my dovii that is only 3'' lol to much maybe but he will need a female sooner or later
