I bought a DeWalt 18V kit exactly like this one on Ebay over the summer, VERY happy with it:
Dewalt DW059K 2 1 2" Drive 18V Cordless XRP Impact Wrench Kit | eBay
I believe I paid $230 Delivered, the lot of 10 (they were new, NOT reconditioned) sold out in a day or two. Randall, you will REALLY like this tool, I have used it more than I thought I would. It makes rotating tires (we're up to 6 cars in our house with kids' cars included) a 5 to 10 minute job.
