DI Box Advice

[Perceval]

I have a Spirit FX 16 mixer and I have access to a 50' or 100' snake (16 XLR sends and 4 - TRS returns). If I want to use the snake to record line instruments (e.g., PODs, keyboards, electronic drums, etc.) then what do I need? Active and passive direct boxes, Lo Z adapters??? If a DI Box, what brand and model would you recommend?

Directions to a useful thread or your sage advice is most welcomed!!! Thanks
