We went with the speed queen tr5. The reason for the tr5 vs the tr3? Two more years of warranty, and an extra option - for $50 more. This warranty (5 years) is supposed to include parts, labor, and fixed at your house. Hopefully we never have to put it to the test!!
We've only ran a couple loads through it. It is noticably quieter than the Whirlpool was, and so far, does a better job.
Fingers crossed.
