Reply to Getting into turnable

Hello
I've been djing for now 6 months with numark mixtrack pro but know I would like to have turnables so I thought about buying :
- 2x Stanton T-62
- Stanton SMX 202
- Novation dicer
So my question are:
Do you believe this a good set to start scratching ?
Do I need a sound card ?
If you have another idea of beginners setup my budget is 600 euros
Thanks
