I do moves the quick and easy way. Drain the water into tubs that you and a friend can carry, move rock into one, coral into another (or several, etc.). I usually put the fish in a 5 gallon bucket or something. As Jason mentions, save as much water as you can to have fewer problems with the move. Try not to stir the sand bed. Break it down, load it up, then set it back up in reverse. I just bought a 75 loaded with rock, fish, and a few corals. We got it broken down in less than 20 minutes. Only moved it twenty minutes away, then had it set back up in 15 minutes (not counting unloading back into the house time). Of course, the guy that helped me has moved more tanks than I have, so we made great time. If you have a pump you can use for draining the tank, that will reduce the move time dramatically. Use jugs for water transport as much as possible. Unplug heaters as soon as you get there so they can cool down before removing too much water, and don't plug them back in until you have the water back in. I know a number of people who have fried tanks by forgetting the heater. As soon as the water is drained below the heater, it turns on (air temp is usually cooler than the set point, so it quickly cracks)
Good luck with the move.
