I have the origional on My router! I can't get down stairs easily, so I am unable to use it on a regular basis! I think that it is great. never mind all the other ones. If I was in good health, I would be able to do more. I need to find the plans book yet. I don't think that I need it untill I look at something realy nice! I know this is an old post, I must of missed it, Had to post on it
