For a DMD I would definitely recommend using an LED over a laser.  Lasers
result in some pretty nasty speckle on the image plane, and also cause a
sort of blazing effect on the DMD, resulting in the illumination on the
image plane being quite non-uniform.  You can also get a 1W 405 nm LED for
pretty cheap:

If you really want some top range oomph, you can go up to 16W still for
much less than a laser:

Here is a picture of the 16W LED in action; you definitely want eye
protection around this thing:
