I've been using the Longacre for about a year now. Love it. Plenty of torque and with two batteries no need for charging all weekend. Full disclosure, I sell them for $255 also with flat rate shipping...
The new version also has LED lights in the base in case you are working at night (illuminates the end of the gun) and a battery charge level indicator.
