What type of T5 lighting would you recommend?

[mechano]

I got a general question about lighting as I am considering the plunge into the T5 world, and finally giving up the MH end.

My questions are:
What would you choose for lighting if your tank was:
24 inches deep and I am looking to stock this new system with generally LPS, softies, and maybe(probably not) some easier to keep acros/sps.
The few I have researched so far include the Tek T5 system with 8 bulbs, and the one with 6 bulbs, I also researched the nova fixtures with 8 and 6 bulbs, I also like the Icecap 6 bulb fixture, but I honestly think if I buy the Icecap fixture my wife will kill/divorce me.

What do you all think? 6 bulb fixture enough? Or the 8 bulb?
(tank dimensions are 48x18x24 inches)
Would you choose Tek, or Nova systems? Do you have a better system that you would recommend?

Thanks in advance
