I purchased the Frigidaire FTF2140 Washing Machine about a month ago and I really like it.  I was in need of a new washer and dryer and decided to buy stackables that would fit in the perfect alcove in my kitchen.  The following factors helped me decide to purchase this model:  

 1). Stackable: But not attached so if, in the future, I decide to put them in an actual laundry room, they can be placed side-by-side.   

2). Front-loading: I like the way it looks and if I decide to unstack them in the future, I could also place them underneath a countertop. 

3). Capacity: Holds 1.5 times more than the standard washing machine.

4). Energy Efficient: This model uses 70% less water and energy than standard models.   During the spin cycle the wash barrel spins up to 900 rpm instead of the standard 700 rpm, which means that my clothes are substantially more dry than when I used my old dryer.  About 15 minutes are shaved off dry time meaning saving on power and time! 

5). Less Detergent: This Energy Star washer uses 1/3 the amount of standard top-loading machines meaning spending less on laundry detergent. 

I really love the washer and very happy with my purchase, but the one downside is that after each load water gets trapped in the detergent/softener/bleach drawer (specifically in the softener/bleach compartments) and stays there until I pull the entire drawer out and empty it into the sink.  I’d rather not have to do this one extra step, but the pros definitely outweigh this one con.
