I am looking at Air Sanders right now. http://www.sears.com/sr/javasr/product.do?BV_UseBVCookie=Yes&vertical=TOOL&pid=00919965000&tab=del#tab and this one http://buy1.snapon.com/catalog/item.asp?P65=yes&tool=all&item_ID=74335&group_ID=831&store=snapon-store&dir=catalog We had the Blue Point ones at school. These things make GREAT air grinders and sanders. My question is, does anyone have the Craftsman unit? If so, can you put a grinding disc on it? I know you can put one on the Blue Point unit, we did it all the time at school. These things weigh much less than an electric grinder and are smaller so they are easier to use for extended times and easier to manuever. I loved them and need to get one for my home usage, just wondering if I could save some money and get the Craftsman one.
