I am about purchase a power tools kit and I trying to figure out which is the better brand between

Carftmen from Sears
Black & Decker from Target
Royobi from Home Depot

Each have about the power tool in the kit a saw, drill vacuum, jigsaw, flash light (I think that all)

Can anyone help

Sears has my vote, among those choices you gave here. My oldest son's boss recommends Sears, unless you have access to to a Snap-On dealer or a Matco Tools dealer. Sears is a very reliable brand, great warranty, and highly dependable.

If you want power and reliability, my vote goes to Millwaukee, that wasn't even on the ballot. If you want something that is so inexpensive that you can throw it away if it breaks, and buy another, check out Harbor Freight Tools, made by slaves in China. They always have discount coupons,

Of the choices you gave, Craftsman or Ryobi get my vote.

Sears Craftsmen would be the best buy for the buck on these middle range power tools, Top of the line Millwaukee, DeWalt, if you plan on making a living with them.
