My two cents worth - just one opinion in many....
If I could do it over again, I would NOT repeat the selection of my 2003 PDW7800. It was top of the line or nearly so back then, and I don't think GE was doing many stainless interiors yet, but the plastic tub is more than satisfactory. Unless a consumer has really lousy water service, I don't know why stainless is necessary. My family has had 9 or 10 Whirlpool / GE dishwashers since 1977 between my Mom, myself and my sister and we've not had a single issue with the tub that would justify or require stainless. One of Mom's was in service daily from 1987 until 2004/5.
On the other hand, I think there are better options than a GE tall-tub dishwasher. Previous to my current machine, I had a 199? GE Potscrubber 1200 for ten years - my most favorite dishwasher of all time. I liked it better than our KDS-17A even. My use habits didn't change AT ALL from the 1200 to the PDW-7800 (to me, PDW means Pretty Darn Worthless) nor did my detergent, but the results went downhill from stellar/perfect to worse than leaving dirty dishes out in the rain.
Since my machine sits for 5 to 7 days between uses, anything that goes in there in the first few days needs to be either nearly clean already or whatever is on the dish or pot is going to dry on there and NOT come off. The 1200 never had a problem with this, nor did my entry level Whirlpool Power Clean from the late 80s.
Recently I have had more success with the GE by selecting the "added heat" button, which helps dissolve the dried on traces. I am using extra detergent too, but I simply refuse to hand-wash items to compensate for a dishwasher's shortcomings.
My machine was an $800-something machine if purchased retail (it came with my new construction house). I wouldn't be surprised to hear of complaints on BOL appliances, but a near TOL?
I recently bought a new Kenmore dishwasher with the PowerClean module - it's in the garage waiting for the day when I have time to do the install.
Overall though, I think there are better choices out there than a GE tall tub. You may want to check the archives here for some of the previous posts on the subject.
