LG's look sleek, but I'd stay away because of horror stories I've read re: repair support. I think Duets are probably the nicest looking machines out there, with Electrolux not too far behind.
My Frigidaire 2140 washer and 1442 dryer just turned five years old. So far, no issues. It would be nice to see them reach ten years old without any problems. I have no idea where my washer spider is in terms of deterioriation, of course. I avoid chlorine bleach and use oxygen bleach only when necessary. I use powder HE detergent only to avoid liquid-detergent residue accumulation on the spider and elsewhere. Still, the spider is aluminum and is going to break some day. The washer itself does a nice job of cleaning while using less water than my prior TL. It must use more water than today's models, since it's no longer on the list of models that qualify for water rebates in our area. The 2140 was introduced c. 2003-4, so the design is nearly ten years old.
