I LOVE my LG Tromm washer and dryer set!!! It's a front loading washer, but we have had no problems. I had thought I wanted a top loader too because it's what I was used to, but I couldn't pass up the deal on the rebates with the front loader so I went for it, and I never want to go back to top loading.
I had worried about what if I find a sock I forgot to put in the load--how can you add it after the load has started already? But it's no problem, you just push pause, open the door and put it in, and continue the wash. I had also worried about reports of front loaders developing bad mildewy smells. We leave the washer door open when it's not in use, so it can dry properly, and we have had NO problems with mildew. You just need to remember to move the finished load to the dryer in a reasonable amount of time. (If you forget about it and leave it in there for days, then you might have to rewash it.)
We noticed a drop in our water and power bills right away. It has been wonderfully gentle on the clothes while getting them good and clean. I can fit a LOT of clothes in it. And the washer and dryer stack to save space. We bought the extended warranty just in case, but haven't had to use it.
Our particular LG Tromm models are outdated now, but they have a range of models and prices depending on what features you want. We went with one in the middle. I've had it for about 3 years, and I am SO happy with it!
