Since you are seeking laundry machine advice on a hot rod forum, we interrupt the advice column with a customization story. When I was a broke college student (round two) I bought a used old-school set from Craigslist for $100. The washer started to leak after a while. I bought a $10 tool at the appliance parts house to remove the big nut that released the drum from the tub. There were little bubbles in the enamel, and pinholes below that. Being broke, I got a $5 can of Kool Patch and fixed the holes. Then put it all back together and ran a couple loads of old ratty white T-shirts to make sure the tar wasn't going to crap all over my clothes. I used that set for five more years until I got married and we spent our gift cards on a brand new set.
And now we return to our previously-scheduled program.
Front loaders are easy to swap clothes from washer to dryer, unless the designer of your laundry room puts the washer hookup on the wrong side, and the brand you buy does not allow the door hinge to swap sides.
Front loaders will stink after a while as the water never fully drains from many models. In our current house, we got a free almost-new pair of Kenmore machines from the previous owner, and saw that there was a class action suit about this problem, but we got nothin' - no receipt. Instead, I run a load of whites with bleach now and then and leave the washer door open for a day so after heroic laundry weekends so it dries out some. Once we learned these two tricks, they have worked pretty well for us. Just beware of the open washer door when you open the laundry room door...
One failure was cleaning the mung out of the door gasket bottom. I scraped too hard and popped the gasket off its rim and that thing was a b!tch to get back in place.
Consider a gas dryer. I had really great luck with the original Kenmore - that thing would dry clothes faster than the electric we replaced it with.
If you buy a set, make sure you remove the shipping bolts from the washer that hold the suspended drum in place to prevent shipping damage. Check the instruction manual...
