That Lowe's 250ft.lbs would be just perfect. That will also be useful for any future suspension work, as those are in the 150-200 ft.lbs range.
Kobalt tools are "made" by Snap-On - probably not the exact same blanks and forgings, but they have the engineering know-how from Snap-On. There is also a mix of US and China made Kobalt tools - sometimes you get a mixed set in one of there contractor or multi-piece sets. I've got a good mix of Craftsman, Kobalt, and Husky sets - I actually prefer the Kobalt and Husky over the Craftman ones, atleast from a price point view. Reviews of them are quite good - and myself, I have nothing but praise for their quality.
They don't hold a candle to older MAC, Snap-On, Allen, Proto, or Matco tools - but as a "hobbyist", can't justify spending a small fortune in tools that will likely sit in a drawer collecting dust.
