Vestax VCI 300 and DI Box

Hey Guys,

What DI box would you recommend for the following setup
Dell Inspirion 1525 w/ Serato Itch
VCI 300
2 - Powered Mackie 15 Thumps - TH15a

I would imagine I would daisy chain the speakers, thus only the need for one XLR on the DI Box? Is that correct?
If so what box would you suggest. Nothing too expensive, but def nothing too cheap.

Thanks
