It is also my suggestion to just watch Craigslist. Just today there was a 40 gallon acrylic tank, with a $550 light fixture, stand and 60 pounds of live rock for $300. If you price LR at LFS, 60 pounds would have cost MORE than $300 by itself! Besides, LR established from another tank is usually a much better buy (its well established and fully cured and less likely to get any undesirable hitchhikers).
