To me that seems like alot of plants to veg with CFL's. You are gonna need a bunch of bulbs. Plus with the higher wattage CFL's heat comes into play, they will burn your plants. So unless you plan to stand around and watch them veg you would need some kinda rocket science idea for the lights to move with plant growth on there own.
My opinion (for what it is worth) you need to be shopping for HID lights. The cost of the CFL's needed to do that would exceed your HID price.
Also check out T5 tube fluoro's. You can get them in 4 or 8 foot lenghts I believe. They may be a little cheaper than an MH setup but I do not think it would be enough to pass up the results a HID setup can provide.
