About to pull trigger. Trying to decide between corded or cordless. My thoughts are if you are going to have a vacuum hose attached anyway, is having a cordless system necessary? Will be used in shop 99% of the time and other 1% probably around house somewhere. Also, from what I see online, Makita keeps a pretty tight reign on the prices. Anyone have a fav source for buying such? The best deal I have found is no sales tax and free shipping (saves almost 7%). Makita is also offering a free 39" track. Not sure what it is really good for as far as sheet goods, maybe good for lumber, so will buy a 55" also and connect.
