Pioneer DJ 2 channel mixer with XLR from JB Hifi for $216 inc. shipping
I did a quick price comparison and found this to be the best deal.
Kosmic are charging $399, while and Lightssounds and Djwarehouse have it for $299 (all prices excluding shipping).
It’s great for if you’re just starting out cause it works just like a pro mixer but is designed for newbies. It’s pretty simple to set up and get yourself going.
