Reply to Newbie Needs Help!!

first of all hello everyone!

long time reader, just signed up yesterday..
i am a 19 year old bedroom DJ from melbourne australia looking to gain knowledge and experience..
but ive reached a dead end,
ive been mixing on a numark dj2go for about a year now (all i could afford being a student)
ive mapped my keyboard to work as hotcues and loops and everything i found i love about traktor.
which is amazing dont get me wrong, but ive now got a job and can upgrade, looking at the vci 380 or kontrol s2..
although im scared my laptop wont be able to handle the club set.. running a powerhorse toshiba pc from a few years back although has to be plugged in cos battery is shit..
so my main question to all you experienced guys is do i need to buy a mac to dj in clubs with??
or should i look at buying a rmx 1000 and just use that to do what i want to do with cdjs instead of forking out thousands on a mac and controller..

all advice appreciated..

cheers
