I have the Craftsman Sawmill and love it. I traded some labor for it and a few other things and I have had it for about 7 years and it still works as good as it did when I got it. I have used it a lot and it keeps on going strong. I don't think the person who had it before me used it much, it never had a scratch on it when I got it, also has a red case to protect it. It was basically New/Used. I am sure putting it to good use though.
I also have a Craftsman 19volt Cordless power tool set that includes the circular saw but I have only used it a few times so far. It works very good. I still prefer corded tools over cordless but the cordless definitely have there place on my tool arsenal.
I have a Black & Decker Firestorm 14.4 volt 6 piece set as well but the batteries in that set suck. I cut with it a few times and the battery is done. The drill works for quite awhile but if I use any of the saws they suck the juice right out of the battery. Not very impressive. It may just be the battery is defective or something, the tools themselves seem to run fine but the battery don't hold juice for very long. I May try another battery and if that doesn't work I will get rid of it.
If you don't mind spending a few bucks then you should go with either DeWalt or Makita, If you want to go a cheaper route I would say the Craftsman is about the best bang for the buck IMO.
