Reply to upgrading my setup tomorrow quick questions!

Hi all new to this community been reading on it for a week now, really good info here! heres my trouble...

atm i have a bcd3000 and a old laptop which crashes etc so i decided to upgrade this weekend.

i was believeing the vci 300 but after reading about them i believe im better off with the vci 100 as i like to use effects and mix beats i will never be scratching....

question is this a good setup that ive been looking at

VCI-100
audio-2-Dj sound card
traktor pro
macbook pro

anything wrong with this setup??

thanks!
