Don't overlook Sears. I needed a 66 gallon electric, and they were the cheapest for one.
If you'll be installing the heater yourself, you may want to get one whose fittings line up with the old one's.
Heaters with 9-12 year warranties usually have two anode rods, one that screws into its own hole and usually a second one that goes into the inlet our outlet pipe. Changing the anode(s) every six years or so should let the tank last several decades.
As Blairsey said, solar water heating can be great, and our system probably saves us $20-30 a month on electricity (no gas available). But costs can range anywhere from $300 to $5,000, depending on whether you DIY or have it installed or need only a simple system (freezing is rare) or something elaborate (colder climates require drain-down or drain-back freeze protection -- drain-back is the best). With gas heat or really cold climates, it's probably best to make the solar preheat the water in a separate tank (no electricity or gas fed to it), but with electric you can get by with a single 50-80 gallon tank. Single-tank systems require a special tank, but instead of spending $1,000 for one, modify a regular tank by cutting its dip tube, disconnecting the bottom heater, and using the drain outlet as both the cold water inlet & outlet to the heat exchanger or solar pump. Sometimes you can get the solar collectors for free because people toss them when their systems break down and they're shocked at the high cost of a replacement solar tank.
