I am looking for a stacked washer and dryer. I would like to have the ones that you can sit side by side OR stack Any suggestions?

Most front loaders can go side by side or stack- the dryer goes on top. If you want to stack you will need to purcase the correct stacking kit for the units.

Washers these days come in both top-loading and front-loading configurations. Top-loading machines are less expensive and easier on your back, but front-loading machines are far more energy-efficient, using two-thirds less water. Both are available in stackable washer-dryer units.
Although they save space, most compact stackable washer and dryer units have fewer of the "bells and whistles" that are available on stand-alone units. Another problem that some users have discovered is that with stackable washers and dryers sold as a pair, one piece is sometimes of a better quality than the other. The washer will break down before the dryer, or vice versa. What do you do when one piece gives out completely, but the other is still good? To solve these problems, some homeowners purchase separate washers and dryers, and stack them themselves. This gives you more flexibility in choosing the features and quality that you want in both the washer and dryer. In order to do this, however, your washer must be front-loading and have the controls on the front of the machine. If the units are full-sized, you will also need a supporting framework for the dryer, and you'll need to make sure that you have enough vertical space to support the whole structure.
