Would love to try that-- would make migrating from the garage to the pit box a whole lot easier!
Or migrating from the truck at the shop to the work bays.
My vote goes for the Makita LXT series. If you look at the charger it seems to cycle the batteries better and Lithium Ion technology can store more energy per mass than equivalent NiCad. The key to good battery life is always being at appropriate temperatures (which sometimes rise on discharge)...
I think the appropriate term is "ignition wrench" wanted for small electronics stuff, prefer the combination wrenches. Looking for SO, Matco, etc. USA Made strongly preferred.
I'm personally a fan of the 2135, the greasing is just one of those costs of having a great tool. I feel like your argument of "buy once and do it right" and "added cost of greasing every 2-3 months" are a bit contradictory.
I rarely use the air impact anymore because I purchased a cordless...
