We have the best luck w/ the dewalts. Make sure not to get a referbed unit and make sure it's the high torque commercial unit not the consumer/ price point model. Dewalt just came out w/ a new charger that will totally drain the battery for you and then recharge to achieve the best charge and battery life. We have found the best pricing so far to be at Grabber on Patterson south of 44th st. We have have real good luck w/ Milwaukee on the larger (cannot remember if 18,20 or 22 volt package kits where you get a cordless, sawzall, circular saw, and one other thing (a light?). We buy those from Hoeksema on 28th in Grandville. Let me know if you want me to check my pricing against yours at either of these places. As you know, sometimes the large home centers sell stuff cheaper than our commercial outlets, just have to make sure you're getting the same models.
