I ordered & plan to use the '3-circuit solution' for both my bikes (1 under seat, 1 up front) for the HIDs & other accessories.
By far the most sealed/compact/cost-effective thing I found. Only drawback is you would need an open-barrel crimper (not a bad thing to have for OE-style connectors anyway, can be had for ~$30).
That fuse block he sells is a great item too, if you need all-in-one.
