Congrats on the syphon, it's a fun brewer and very entertaining too! (great for when friends are over)
The butane burner's are ideal as you can control the temp fairly well.
I personally cannot recommend the hario hand grinders, the quality is poor and you'll be in the market for a better one before long.
On a budget, I would suggest the PORLEX grinders. They are tough and just better quality all over.
If you can stretch your budget I would recommend waiting four weeks for the new Comandante hand grinders to land in Oz. I had the opportunity to check them out at the expo in Melbourne and have to say, they are incredible. Double the cost of a Porlex however!
For syphon params, you could try:
15/16gm of med-fine grind
265gm water; then:
heat water, affix top chamber, let water rise. lower heat source so the water still sits in the top chamber, stir top chamber a little to drop the temp. Aim for 88-92C up top. Try your best to remove all bubbles from the top chamber while the heat is on, gently position the filter with a paddle/spoon until the bubbles are gone or mostly gone
drop grinds in, gently submerge with a paddle/spoon, steep for ~35 seconds
remove heat source entirely at 35sec and gently help the brew in the top chamber drop with a little agitation/stiring.
let cool in bottom chamber or transfer to other jug/carafe for serving after about 5-8 min of cooling.
clean your cloth filter with water and keep it damp, inside a sealed container
mmmm, I'm drooling right now.
