Lighting and hydroponic system questions

Hey guys, I am a first time grow and have never actually did it yet. I am currently trying to figure out everything I need. After looking through this forum I have decided on two lighting systems. System one is a CFL and system 2 is a 150 watt HPS. System 2 cost about 40 more and I was wondering if it would be worth it to spend the extra cash on system 2. Can I use HPS for both vegetating and flowering or is HPS only for flowering?. Any advice or tips would be appreciated. Please let me know


SYSTEM 1 - http://www.ebay.com/itm/251401254974?ssPageName=STRK:MEWAX:IT&_trksid=p3984.m1423.l2649
SYSTEM 2 - (150 watt)http://www.ebay.com/itm/400192553185?var=670006135310&ssPageName=STRK:MEWAX:IT&_trksid=p3984.m1423.l2649

On another note, I am think about buying this 6 site hydroponic system. Its cheap and has everything, so it might be good for beginners?

Please let me know what you think of this also.

HPS is far superior to cfl, cfl is cheaper to buy and uses less electricity, If I had a choice I would use HPS. You should keep it simple initially, you may buy something that doesn't work for you. Remember that there are pro's and con's to both HPS and cfl.

thanks, I think im gonna go with the HPS light, anybody of any feedback on the hydroponic system?
