Juli, I got a front-loader about 5 years ago and have never had any problems with it. It uses a ridiculously small amount of water and cleans very well. It also uses a small amount of HE (high efficiency) detergent and is energy efficient, so altogether it costs me very little money to do laundry. My mother has a traditional top-loader, and I can't believe how much water it wastes! I think there are top loaders now that are more water efficient.
I've never had any leaks or odor problems, but I DO leave the door ajar. I think keeping the door closed causes odor problems on some washers.
I've never had to soak anything to get it clean, so soaking has never been an issue.
You don't need a fancy machine with all the settings, but I would recommend one that has a "sanitary wash setting" or something similar if you're thinking about doing heavily soiled linens.
Oh, and I'm also vertically challenged.
