Hey I need one now that I've got a boat to mangle.
Some to look at are:
Panasonic EY6432GZKW $200 and the Ryobi P813 at $170 are really godo if expensive. The Makita BDF452HW $200 is only 3.5 pounds.
If you want to be really manly, then the Hitachi DS18DMR at $200 and 6 pounds is the way to go or the Makita BDF451 at $280 is nearly a pound lighter.
Finally, if you don't like turning screws, then the Ryobi HP472K seems like the best choice at $30.
BTW, Craftman are only at Sears, Ryobi only at Home Depot. While Hitachi is only at Lowe's. You can get Makita at Sears, Home Depot or Lowe's.
