I do both with cool tubs... but 400w will work and 600w is harder to cool with no help. So a 400w will be the cheepest and better suited.

60+ watts per square foot or you'll be disappointed.
2 x 600w

I would go with 2 -600w along with fans to keep the temps down and the air moving.

The general rule of thumb is 40-50 watts per sq. ft; I would go with 2 -600w along with a couple of fans to keep the temps down and the air moving.
2 x 600W HPS
To echo others.
Get some dimable 600W digital ballasts and run them at 400W during veg and then switch to 600W during flowering.
Presto! You are set.

Depends on the style of grow; many variables, strain,time in vegging, etc. Lots of good ideas in the newbie sections here. Rastafari
get a dimable 1000. you will never know when you are going to upgrade (we usually all do) and prices are not that different. run the light as high as possible while keeping temps in check. it's common to run more watts in the winter than in the summer. with an adjustable 1000watt ballast you will be able to reduce the watts or even boost them by 10-15% when condition allow. your hvac will dictate that. get a good hood too!
i have a bunch of 400s and 600s collecting dust. we even upgraded our veg room to 1000w MH. plants grow much faster and we have the ability to dim down to 500w.

I'd go for the 1000w dimmable also
you'll find a use for the 1000w setting sooner or later and i'll be it'll be sooner
BUT
if your 1000% positive that you'll never ever use the 1000w setting
then i'd consider a couple 600w dimmables
the 1st time you move your babies from the T5s
and put em under 1000 watts of pure MH goodness...
and experience 1st hand the explosive growth you'll wonder why you didn't do this loooooong ago
