Part of what makes a good deal on a tank is what the cost for a new setup thats simular costs locally. Prices for tanks can be widly different depending on where your located and in some areas a $50 price on a 29 gal
tank, stand, hood an filter is an excellent deal because the price for something simular new would be 3X that if not more. Where as in other areas that price is not that good because the same thing new might be under $100.
For me it would probably be a judgment call based upon the preceved quality of the tank and the stand. If the tank and stand both appeared to be in good condition then I would consiter the first a decent deal. The $60 for a 29 I would pass up on.
