I sent my Bushnell back to Cabela's today, so if they're in stock, I imagine by the end of this month perahps. I had planned on getting the 4.0 as well, but since I'm returning something that cost more than the 4.0 as it is,I figure I might as well go bit further. I'm looking forward to quit messing around with the 6 volt battery mods. It'll be interesting to see how it stacks up against my '05 Cudde.
