I'm sorry you have a bad experience! I'm still very pleased with my 2032mw. I use it as my TV as well. I don't have any problem with the build quality; mine has a very sturdy foot and stands very stable.
About the picture quality; as I showed in my pictures (which are like I said of RTG screens), they are of good quality, at least in my opinion.
I still have to try AGA screens; I'm waiting for my S-Video adapter to try it. I will post when I have more info! What connection did you use for the Amiga to the monitor?
Once again I'm sorry you had this bad experience; I feel kind of guilty...
