Both are really good technologies, the only reason I have not bothered to check out DLPs is because I can see rainbows. If you can't see rainbows when watching the Mits (literally, you would see rainbows), definitely check it out.

Here is a website about the rainbow effect...there is a link within the article showing a video of what the rainbow effect would look like if you could see them. (Be happy you can't!)

As JCL said, the technologies are changing VERY VERY quickly.
