[2.2 Straight six]

IR Guns are the best i've come accross, i own two of their 1/2" composite guns (a 2135QTi and a 2135QTiMAX) and they've never let me down, they've been money well spent even if they were expensive. 1,100lb/ft ultimate torque from a 1/2" gun is more than you're likely to need, but it's handy to have it for those rare occasions like working on commercial trucks or stubborn harmonic damper nuts.

Carftsman tools will hold up just fine for daily use, so long as you look after them. they may not be as strong as Snap-on, but so long as you don't abuse them they'll last. my impact sockets and lots of my chrome sockets are similar quality to Craftsman (they're Draper) and they've never let me down.

for Impact sockets, i'd go with Ingersoll-Rand, they do a big shallow/deep imperial/metric set that's a good price, it covers just about everything and IR cover them with a lifetime warranty, and from what i've heard IR and good with their warranty. i'll be getting that set soon, and the other good thing with IR is that they do everysize, so even if the set doesn't cover it, you can order the missing ones.

if you want to get Snap-on, look on eBay. i've bought most of my Snap-on stuff from eBay and saved a lot of money.
