Reply to what controller for $300?

I'm a bedroom dj and I've been using Traktor Pro with the keyboard and mouse and now I want to upgrade to a controller. I mix trance and house and use effects, loops, multiple cue points, and the filter a lot, so I need a controller with a lot of buttons.

I was looking at the Vestax VCI-100 and it looks pretty much perfect, only downside is that it doesn't come with a sound card. I mostly just record my mixes for myself to listen to so a sound card isn't necessary right now, but it would be really nice to have for parties and such! Basically I'm wondering if there's any controllers with a sound card that would be suitable for me and are high quality at around this price point, and if there's any reason to avoid the VCI-100. I'm looking for something with a nice feel that would really make the transition from keyboard worth it, if that's possible at this price point.
