I have a couple of DLPs and one direct view HD and none of them have this problem.
I believe what you are talking about is the response time. They all have a delay, unlike CRT which basically lights up almost instantly. I am sure someone will be along shortly to explain this in more detail, but basically, as I understand it, the response time is how fast the pixels of an LCD align to display the image.
I thought they had gotten a lot better on this. I just looked at the brands, and most of the models even the cheapo's, average about 8ms. Even the Sony's are 8 ms. I think only the really small 19" models average lower. Though, Sony has a new "120hz" model coming out in April that claims to reduce motion blur, so if they needed to make that model, then obviously you will still see it in the 8 ms entry level models.
So, it's not really a result of a cheap brand. Polaroid in a side-by-side (and granted this is in a store where their feed is probably all split up), you can really tell a difference between a name brand like Sony and your Polaroids, Sanyo's, etc. Sony has been at it for so much longer, so they can produce a really good picture, but as you said, the motion blur is always going to be a problem, especially the bigger the screen is.
Now, the people that will come in here arguing this will be the owners of the upper end Samsung's, but the real argument here is the average TV. I mean who really cares once everything gets above $1,000, you have many options for TV. The thing is, 3-4 years ago, you could spend below $1,000 and still get a really nice TV. Vizio, and Sanyo, and all these cheapo LCD makers ruined the market by offering LCD to that market, which should have been owned by CRT.
