i would personally just get a computer, soundcard and monitors first. when you feel comfortable with software and producing, the decide whether you need hardware. Before you get drum machines and synths i recommend getting a mixing desk and outboard compression then take it from there. Learn to use each piece of equipment you buy before you get something new. There's no point buying a shit load of hardware and not being able to use it. If you do wanna get a drum machine though, i recommend a Jamox X-base 09, wicked analogue sounds.
