UV sterilizer

[Coasting]

I'm looking to add some sort of UV sterilizer to my new system. Something that will deal with 100gal or so of water, give or take... I would rather overkill then under do it....
I'm looking at what our sponsors have available, but leaning towards what J&L carries because their nice and close. That would leave me with the coralife or Pentair, BRS has the Emperor at 50 or so more.
What would you go with? what would you stay away from?
Ease of getting bulbs, ease of cleaning, ease of setup.
This will not be hard plumbed into anything, will end up running somewhere in the sump like the skimmer.

And what would be a good pump to go with whatever UV ends up being the one?
