Thanks for the input, these are some of my concerns, I don't want to be spending $350 for something that won't last me. The new Strikemaster seems to be better, so I think I'm going to end up going with that one. I figure if I drill a good dozen holes with it I can just have a bettery out on the ice with me to charge it while I'm not using it, thus keeping it from ever hitting empty. A 12 volt is what is recomended to charge it, but I'm sure I can always go bigger, I havn't got it yet so any more info would be great especially if anyone out there owns one!
