Ehh. Might just be cheaper to get a kit than go for the $1/gallon sale anyways.
gotta think $55 for the tank, plus paying for a filter, hood, lighting, etc. You'd end up spending more than $150 in the long run if it is quality equipment...
But I personally cannot tell you how good of price $150 is, the biggest tank I have right now is a 26 and bought that on craigslist for $20
