Browsing the LumberJocks forum, I have found that Hitachi sells reconditioned tools for pretty good deals compared to buying brand new. Reconditioned tools are pretty much new tools, they are tools that have been returned by customers to the retailer. They are all tools that could have had defects, been returned by an unsatisfied customer, returned after a weekend project, some returned brand new just because. When a tools is returned to a retailer, they cannot just put it back on the shelf, instead they have return it to the company. When this happens the company, in my case Hitachi, fixes whatever was wrong with the tools and sells them at discounted prices.
I think this is a great way to buy like new tools for great prices. The tools come with the full factory warranty.
I ordered two tools from Hitachi, both of which have great reviews on different websites like Amazon and LumberJocks. I bought the Hitachi DS18DFL 18V 1.5Ah Lithium Ion Driver Drill for $109 and the Hitachi NT50AE2 2" 18-Gauge Brad Nailer for $53 since both of mine where stolen.
Seems like a good deal to me, we will see once the tools get here!
