Yeah, l had the same problem.
Didn't know where to get one in Sydney. So, l just e-mailed chemical generation and sent some money. There is a place in Manly l think that sells them. They said that Reachin' Records on Oxford St sold them, but they only had E1 kits.
Good luck, if anyone out there knows where to get an E2 tester, in the CBD (if poss), can u please post it here....
Thankx
