I don't think his issue is solely how much it is, it's the whole "why buy an expensive gun only to have to spend a shedload more it", to that end I'm in agreement, in much the same way I cringe when a new member posts up "just bought a new gun, not used it yet, what should I upgrade ?"
FFS, get out & play with it, whether it's a £100 gun or costs £1k, it'll usually do exactly what it's supposed to within the boundaries of physics, no amount of money spent will surmount the laws of physics while staying within site FPS limits ?
