Dboys used to sell over here but went away a bit with the clamp down of Chinese clones. It's very much a lower end gun though, below a jing gong which was comparible at the time, they sold for much less than £300 though, more closer to £100-150
Their AKs were pretty good but with a budget of £400 a dboys isnt something that I could recommend which the likes of g&g, G&p, kwa, tm etc
