Which short course???

[martylaa]

Fancy a basher and like the looks of the short course trucks, thinking of one of these:
Traxxas Slash 2WD 1/10
Traxxas 4X4 1/10
Associated SC10 Brushless RTR Rockstar 1/10
HPI Mini Trophy Desert 4WD 1/12

I did see a Associated 4WD version but its pricey. are 4WD cars worth the extra???
Its my first car as well, running it in the street, dirt tracks, garden etc, may in the future fancy some racing if i can find some local clubs?
