In australia,
meth=methamphetamine, usually high grade stuf
also known as crystal sometimes ice if you dont know what you are talking about.
Speed=methamphetamine, only cut to shit so it feels weaker, its exactly the same stuff.
Ice=4-MA, potent stuff and fairly rair.
or if you are the cops ice=meth , they report busting 1.96kg of 'Ice' a few months ago, it was meth, the cops dont know dick about street names, they use meth and ice interchangeably, because they thinck that ice is the street name for meth.
trust me when i say this, few people would actually go to the trouble of actually making amphetamine sulphate when they can just as easily make methamphetamin HCL and sell it for twice as much.
As for the price, if you get say 3 decent hits out of it, ie keep you up all night you got a good deal, use this as a guideline.
