Bob, you'll remember that I bought a sliding compound miter saw at HF a couple of years ago. I bought it specfically to cut HardiPlank. HardiPlank is a cementious material and the dust will chew up power tools as fast as anything you can imagine. There was no way I would use a $600 or higher saw to cut the stuff if a $200 saw could do it. As it happens, I got the saw on sale for $100! Well, here's the update -- I couldn't kill it. I used it to cut the siding for all 4 walls of a 1200 sq ft building. Then, I brought it home, put in a new blade, and have been using it to cut laminate floor planks to length, a fairly precise task. Working great.
