Aquarium controller or individual controllers?

[lastlight]

As the title states I'm considering my control options here. I'm looking at either buying

1) a Profilux II or Aqua Controller III
2) Individual controllers such as a dual-stage Ranco, Tunze 7095, digital timers, pinpoint ph

The appeal of the all-in-one solution is obvious. Also (in the case of the Profilux) the sex-appeal is staggering. My concern is a failed controller. The Ranco for example has been proven to be rock-solid. It'd be nice to keep my system mostly operational and replace a timer etc rather than manually do EVERYTHING the all-in-one controller did.

Please vote which you would go with if money wasn't your primary driver. And share why =)
