challenger chasin'

heya gang, i've had a win with the missus, she gets another room built on the house, i get my bigger shed, and I'M ALLOWED ANOTHER CAR!!! have been playing with aussie cars for a while now (2 valliant chargers, 1 vg 2 door, 1 lc gtr torana) and am thinking some us muscle. i am quite partial to the e74 challenger although i don't have funds to support buying an origional, however, what's stopping me building a clone, who's gone down this road before, would i be better buying a roller in aus (bout 10k if i'm lucky) or should i be looking at importing one? all sugestions welcome as at the moment i could be swayed even towards another model/option, would prefer a bigblock but if say, a T/A came along for the right price, i'd be keen too.. whaddya reckon chaps?
