Hi,

I am looking at buying a second hand mac in order to make music. I am a DJ an would like to experiment in making beats myself. I have used reason on a PC and felt comfortable using it. I now want to buy a mac and I believe in this day and age that I need to be looking a a G4 /800Mhz in order to use reason , cubase and plug ins including atmosphere. I have a budget of 700 pounds . Are my requirements reasonable? What can I expect for my cash? and what should I look out for?

Any advice will be greatly recieved
