Performance parts down under

HI! I´m wounder if anyone has bought parts from XSpeed Performance Center in Australia? I´m searching around for hks cams and springs,and I discovered that XSpeed have very good prices. Anyone that have had trouble with XSpeed?
I have good experiance with other companies in Australia, like Tweak It,they are great!
Thanks

Theres an Xspeed tuning house not too far from me and i've used there dynos before. I've only hearded good things from the company and they have built some insane engines in the past.
