Not really a good deal. I have found that these packages like this where they bundle everything either are overpriced or have products that are inadequate. This is a case of the products being inadequate. I have serious concerns about that fan being able to pull through a filter. I also do not believe that a 4" fan (any kind) and filter will be adequate, especially with a batwing reflector. I would never buy a light that you cannot air cool and would never recommend that anyone else do either. I also like digital ballasts over magnetic ballasts. There are several advantages to them.
So, I am going to suggest that you look for things "ala carte". Find a tent you want. A 100 x 100 will be fine for a 600W light. However, I would recommend a digital ballast that will fire both HPS and MH lamps. I also recommend an air cooled hood or a cool tube. You will need a 6" fan and filter to keep the 600W cool.
I believe that you are going to be able to set up a space with decent equipment that will do what it is supposed to and stay within your budget. But, do not scrimp on the lighting or ventilation. But there are a fair amount of miscellaneous things you need that add to the overall cost--pots, soil, soil amendments, nutrients, timers, meters, fan speed controller, ducting, and a few other things that I can not think of now.
