$400 is a GREAT price with a one year warranty, We would charge $600 for this pair with the one year warranty, have you guys looked at the prices for TOL washers and dryers lately? This is not some one selling old machines that they replaced because they were starting to have problems.
I'd gladly pay $400-- I'd pay $600. Those are TOL machines in great shape. My mother loves hers and the only thing she has had repaired is the lid switch on the washer. I think she paid around $1100 for the set when they were new in 2001.
