If i ha no system and came into $1500 i would buy...
A mill, base, hopper and motor $250
140L alu pot $200 (http://www.aussiehomebrewer.com/forum/index.php?showtopic=52148)
nasa burner $30 in bulk buy
stand $150 (scrap metal and a mate welding)
shyhook and pulleys $50
some hops from hops direct $100
5 bags of grain $200
fridge $0-100
temp control $35
3mx1.5m of swiss voille $18?
Keg kit $200
co2 bottle $180
$1513
This would give me a system that could knock out 4 23batches a brew day (ie 10 cartons of beer) with the convenience of kegging. 3 brew days and its paid itself off! When i was working this all out i didn't have the kegs on there but i realised i had about $400 left over so why not. If you are going o spend the whole lot on brewing gear then this is what i would do.
OR
I would snap up this bargain
http://cgi.ebay.com.au/HERMS-Brewing-Syste...=item3a62ee5f13 and get grain, hops, temp control etc with the left over
