Right, which is why if you DYI-It you can't get a tax credit for your labor, but if you pay a contractor you can, so when figuring overall costs it could make a difference.

We added insulation to our attic this year and with tax credits it ended up being the same cost as materials alone at the local hardware store and we didn't have to spend time up in the HOT attic with itchy insulation.
