I've been using my DC 550KA for about a year and like it a lot. Just wanted to pass on this tip: I wanted to go with a larger than the 1/8" bit because I was breaking it often. Dewalt only has the 1/8" and 1/4". Rotozip makes a 5/16" bit but it wouldn't fit in the Dewalt collet. If anyone else wants to go to a 5/16" bit the Rotozip brand 5/16" collet will fit the Dewalt DC550KA just fine, so you can use the larger bit.
