Been having a lot of trouble with my scroll sawa lately. Don't know what the problem is, but I've been through 3 tensions rods for my Ryobi in the last 2 weeks. I use my 24" craftsman, but since it only has 2 speeds, snail and lightning, which lightning is just too fast and snail is too slow I go through blades like crazy. So, i gave in and ordered a Dewalt 788! I will get it before the 29th. I know the majority of you have one, is there anything I should know before using it? I'm excited!!!
