Query: Get the Wave and save some cash.

I owned a Ti and it was stolen so I bought this. At the same time, I bought a Wave as a gift.I was surprised to realize that these two tools are identical.The Al/Ti charge versions, have much cooler external panels, and they come with a gift tin etc. But if all you need is the tool and don't care about the cool factor, (The Al IS very cool looking - I'll give it that) get the Wave.The wave and charge have the same features, and the same internal build. Only the outside panel is different. The Al might be a tad lighter, but not enough to make a difference. For THAT, get a skeletool.I 4 stared it, because I think it should be made clear that these two models are very very similar...
