To really do this set justice, they need (in addition to Owen Lars and 3 x Jawas): C3PO, R2D2, Gonk droid, RA-7(one with a proper insectoid head, not that black C3PO headed rubbish that we got with the Death Star), the R2 type unit with the conical head (that "has a bad motivator"), the spider armed one, the one that was basically a dome and an aerial on wheels, R1G4, Aunt Beru.
I hope this is one of those sets that looks far better in the flesh than it does in those pictures. It doesn't look incredibly large at about 58 studs long, not for $350 (likely £250/E300). how many of the piece count will be swallowed by those treads? Not impressed with the lazily placed 2 x 1 yellow trans plates for the cockpit windows either.
