Right now, I can buy a 240 gallon with stand, filters and heater for $240. Also I can get a 125 gallon for $125 and a 150 gallon for $150. All of them come with stands, heaters, filters, rocks, etc.
About a year ago I got a good deal on a tank too. One of the LFS was having an out of buisness sale. We got a 150g corner tank with stand, heater, filter, and light!
beat you all! even though its a 5 foot 110 i still got it cheap! 110 glass, one eheim 2250, one magnum 350, light, food, meds, and bunch more, and stand for guess how MUCH! 65 buxs from C-list! that was 6 months ago! the guy orignally wanted 300 for it. then talked him down to 100, called back 2 weeks later and said i got 65 buxs in cash, he took it. so i think i got a good deal!
