I love the look of mine. There's a certain 'friendliness' to it-- I mean, it's already a weird looking rifle, why not make it a different colour too?
Like Madness said, they show dirt fast. The brass deflector on mine is turning dark grey/black, and you can totally tell where I put my hands while cleaning it.
Make no mistake though, everyone on the line will come by to take a peak at the "white plastic toy."
When I bought it, my first question was about the cracking. They said that it really shouldn't be an issue and it was more likely related to defects introduced in the manufacturing process (as opposed to the plastic just not being strong enough). I haven't put enough ammo through mine to confidently say that it won't crack-- but I have faith.
