Karuhi,
Steve doesn't have an agent in this part of the world so you would have to order from him directly.
Look about halfway down the page
http://airgraver.com/Hand_Engraving_Tools_Overview.htm
to find the manual push kits and starter sets but I would also look at getting all of the diamond stones to grind down and polish the gravers. Later you can expand the range of sharpening templates. As I said before if you were to get some traditional gravers (ie. lozenge, knife, flat or round) they will not fit the sharpening templates and one of the greatest problems newcomers have is the ability to sharpen a graver to a consistant angle.
There are numerous posts from newbies wanting advise - try this one

Don't forget to keep looking on the forum as occasionally someone has to let some tools go - but be prepared to pay for freight - same goes for ebay.
Good luck,
Roger
