I stay away from yellow cordless brands I'm a Panasonic man when it comes to cordless. IMHO better build quality and better batteries than other I've (mis)used.
I've got this. Nice 3 in 1 combo for my use. Good batteries. But maybe a bit slow for drilling, but ok for self tapping (in metal) screws.
My brother had this at work. He was very pleased, better than the Hitachi he had before.
Check out ebay.com, I bought from a guy called themidwestmustang, and paid about $ 65, including coilpacks and shipping to New Jersey. And another £ 30 for shipping and taxes to Norway. And just to make some more confusion about currencies, thats about 800 norwegian kroner alltogether.
I will go down the same EDIS route myself in a couple of weeks years, and this looks like the right way to go regarding plug leads, but was it costly? under £100?
