Out of curiosity, what makes 42030 better than MB Arocs (42043) or Mobile Crane II (42009)? I was just looking for a gift for myself a week ago, and 42043 looks great.
42043: - contains the pneumatic pump & tubes which are less common pieces - this is the only other large technic set I've bought (and I got it mainly for the pneumatic parts)
42009: - Lots of beam parts, but not many power functions parts included.
