I have the Dune Runner version, and I'm quite happy with it. The Robot mode is pretty awesome; while probably less articulated than Landmine, I think DR looks less awkward in robot form... I think it's mostly the chest on LM... it looks too much like it comes to a single point, where on the DR mold it's more flattened, like an armoured vest.
I think the DR mold was perfectly suited to the Beachcomber re-paint, but this re-paint just seems like an excuse to re-use the mold. Also, the thing about the movie line is that it seems to me the heads are done in two very distinct styles; Autobots which look a bit more "friendly", and Decepticons which look fearsome/harsh. For a good example, look at the difference between Bumblebee or Ironhide's heads, and that of Barricade. Could you really see Barricade being re-painted into Prowl? I think not.
This leads me to my point: The Scout class seems to be the one area where they are doing "cross-faction" repaints. However, I think two so far are a bit weak. Crankstart's head just looks way to "autobotish" to me, and the heads of Nightbeat and Slapdash look too "decepticony", which makes sense considering they were made from a mold that started off as the Decepticon Dead End.
Sonar/Depthcharge seems to work either way, and I think that the forklift Dirt Boss mold could also wear the
convincingly, but this DR repaint just doesn't do it for me, and I really like this mold.
