No specific suggestions, but buying locally can still be a money-saving proposition. It takes some luck and timing, but remember that many LFS have sales. Even without sales, many local stores offer discounts . . . one LFS had stands at 50% off if you bought the tank . . . another said they gave good price breaks if you bought a "package."
Almost bought our tank in town because I stopped at one of the LFSs and they were having a sale, that was ending that evening (about three hours). Wasn't able to pull the trigger right then, but about a month or so later were out of town on other business and stopped into a store there on a whim, and were confronted with huge colorful signs proclaiming a giant tank sale. Next thing I know, there's a 90g AGA RR tank, stand, and canopy being shoved into the back of my wife's Highlander.
Shipping of something as heavy, bulky, large, and fragile as a tank would have to come close to negating any savings in price, may even exceed the final total locally. Risk of damage, as well as the hassle of dealing with any problems is also larger with something bought from far away.
Buying used can be a crapshoot . . . sometimes great, sometimes not so great. If you do buy locally, see the tank with water in it, as well as any plumbing/equipment hooked up before laying down your cash. Don't just buy a tank that's been sitting in a garage without seeing it filled with water, and watching it for a while to see if it leaks.
