a hyper 8 from perth is about $615au delivered thats were i got mine.a mugen prospec would be about 1200-1400au from complete hobbies in adelaide and you can pay about 900au for a mugen prospec overseas so if your gonna get the mugen caroilnasrc in america will be the place to get it from

hyper 8 is cosiderably cheaper and the quality is there in the kit it just depends on what you want both cars are good enough to win

not sure about the eb4 s3 price
