Reply to VCI-100 - questions please

Hey guys,

I used to use Torq with the Xponent but I'm getting rid of it and want a new solution. I hear the VCI-100SE from Dj Tech Tools is really great and I believe it will be best for my needs. A few questions please:

If I get a normal VCI-100 to make it the same as the VCI-100SE do I just buy the overlays and update the firmware, is there anything else?

I assume I need a soundcard with this as there is none built in. What ones are popular? I was believeing of the Native Instruments Audio 2 DJ - will this be ok?

Are there any other controllers that I should consider apart from the VCI-100?

Any advice appreciated
Thanks!
Colly
