I paid $378 out the door for my All-Glass 40 Gallon Tall, Jager Heater, and Eclipse 3 hood/lighting/filtration system, 50 lbs of blue gravel, and a nice all-glass wood stand. I thought it was a pretty good deal
I would go to some of the major companies such as oceanic and all-glass and look for a local reseller in your area. around here i know petsmart sells oceanic tanks, but they dont look the same build quality as the ones i see in my LFS
Craigslist is hit or miss, i have seen people advertise tanks as "mint" only to get there and find it with a sealed hole and the seller saying that "it doesn leak". I looked at at least 15 craigslist tanks without success before finally just saying forget it and going to my LFS
and buying my setup.
