Apparently the 8043 Motorized Excavator has been pulled from shelves. I don't know all the circumstances yet, but you can't buy it anywhere now. Which mean that the one I just bought last weekend is "Limited Edition." Makes me wonder if Lego will be offering replacement parts, re-release it or just discontinue it altogether? Hmmmmm.
I am up to step 23, so I am pretty early in the build. I am going to very closely inspect each step as I go now.
