This isn't what you were asking but when my washer died I bought a front-load. Paid for it in 6 months same as cash.
Anyway, I cannot believe how long my detergent lasts! You only use 2T of dry per load or a tiny amt. of liquid. I was flabbergasted at how infrequently I have to buy detergent.
And my water bills, all that are down. I really love that front-load!!
