I know you said you like the top loaders. I did too and thought the high efficency washers were a gimmick. But, when I did my research, I found out that the high efficiency washers were a great value.
They do cost more, however in the long run they pay off. High Efficiency washers use less than half the water that top loaders use. I was told a full load uses ~13 gallons versus a top loader that uses ~50 gallons. That means, lower water costs per load.
If you wash in warm or hot water, that also means a reduction in electricity useage. In addition, because they spin so fast the laundery cycles can be shorter becuase they clean the clothes better. Lastly, the spinning also means that the clothes are dryer at the end of the cycle, so you spend less time drying a full load (another energy savings). What used to take me a minimum of drying for an hour, now takes me 35 minutes.
All dryers are built the same. They're all 220v, and you can buy any one you like. No need to spend extra money on one that matches the HE washer (but a matching set is pretty), which they charge extra for.
Kenmore has some great brands. I shopped around and got my best deal somewhere else, however. Kenmore sales reps make commission, many other stores' employees do not.
I hope you find something you love and works out for your family!
