Or one of those cheap all in one units.
You may think buying one will save you money, but it won't.
1. They have very little resale value & are hard to sell.
2. They break easily.
3. Using such low quality equipment is more likely to turn you off to wanting to stick with DJing.
What you need.
1. Wires
2. Microphone (optional)
3. Headphones
4. Mixer
5. A Dual CD Player or Two CD Turntables
6. Digital Effects Processor (optional)
If you don't have them already, you'll need to buy wires.
