Thanks for Input; But No Thanks to HE4t
I am locked into a purchase with Lowes, as I purchased the Neptune through them and they are agreeing to an return/exchange. That, of course, eliminates the HE4t. In addition, you know how trying to make a decision can really drive you wild! I am now comfortable with getting either the top-of-the-line Duet or the comparable Kitchenaid machine. My decision will be finalized by the cost difference between the two units. If I don't get any discount on the Duet, the Kitchenaid would look like the winner.
Aside from the above issue, I had considered and eliminated from contention the HE4t back when I was doing my initial search. Two reasons: the Sears salespeople explained to me the difference between the Duet and He4t. Somehow, I felt more comfortable with the Duet. Other reason: whatever machine I purchased, I wanted to get a total of 5 year warranty. A purchase from Sears would require at least $300 extra to get that coverage whereas the coverage from other places would cost about $100. Now I know the argument that Sear offers more than a warranty and I will concede that. It still comes down to if you purchased something that cost $1,100 (cost of Maytag Neptune), it would seem reasonable to spend $100 to insure for 5 years. To spend $300 to insure for five years seems less reasonable.
Having said that, I applaud Sears as their sales people really are on the ball! For anyone trying to get up to speed on what is available in washers, I would recommend that Sears be Stop #1.
