Product review (4 stars): Heavy Wash is Excellent
UPDATE:  12/2/15 -- I purchased my Amana ADB1100AWW on 8/6/15 from a local Home Depot, as it was on sale and included delivery and installation.  After a few months of use I can confirm that this affordable Amana does an excellent job, as long as you use the Heavy Wash cycle.  While it takes longer, it does a very good cleaning job and is much quieter than my old GE.  The Normal Wash left food residue even after items were pre-rinsed, and seems to exist only to impress the EPA.  I'm happy to say that going for the cheapest dishwasher available turned out to be a good choice for me, since I only use it once a week when it's full.
