i sell appliances full-time for a living, and the LG steam set are my FAVORITES. they are super-reliable, the largest front load capacity on the market, and not only do they have a "steam fresh" cycle for wrinkles and odors, but about half of the cycles of the washer have an optional steam element to them. since steam particles are much smaller than regular water particles, the steam penetrates fabric better to get out stains and things like that - it's a much more effective cleaning mechanism. like hubbawubba said, it also has an internal heater, which when set on the 'sanitary' cycle, will heat the water up to about 167 degrees, which is the temperature necessary to kill pathogens and bacteria on clothing.
the most high-end LG steam set (the ones with the LCD display) spin out, at the highest, at about 1320 rpms, meaning that the load of laundry you put in your dryer is much dryer, which reduces drying time dramatically and also lessens the wear-and-tear on your clothes. additionally, the washer uses between 10-15 gallons of water, depending on the cycle, whereas a regular top-load washer will use 40-50. 90% of the energy used by a dryer is to heat the water, so ultimately, you'll save a TON on your water an energy results as a result of the machines. as a result, you'll need to use high-efficiency detergent, or you'll mold out your washer. HE detergent lacks the phosphates that make regular detergent bubble, which also makes them better for your skin.
LGs are also magnetic drive motors, which reduces vibration at high spin speeds over a belted system and makes them less prone to needing repairs.
as far as a mildew smell goes, this happens to most front load washers for two reasons: the consumer is not using HE detergent (it's a MUST) or if they are, they're not letting their washer vent properly. top-load washers don't seal to be water tight on top, so they can dry out effectively. because front load doors MUST be water tight, if you close the door until it clicks after every time you do laundry, it won't dry out properly and can cause mold. to rid your washers of the smell, run a regular cycle with ONLY bleach instead of soap, and then wipe out the gasket with a bleach wipe - to get it to not come back, let your washer stand with the door open for a few hours once a week or so.
in America, the most high-end set with pedestals will cost you around $3300 after 7% sales tax (i sold the pair to a woman yesterday, so i remember). i don't know what the exchange rate to the canadian dollar is like, though.
if you or anyone else has any questions about the machines (or any appliances, really) feel free to ask here or PM me.
in my opinion and from the reviews i've heard from customers, they're worth every penny if you can afford them.
