Quick light question???

i was looking into getting a GROW mh/BLOOM hps T5 COMPACT FLUORESCENT LIGHT system that they have on ebay for like $100 http://cgi.ebay.com/GROW-mh-BLOOM-hps-T5-COMPACT-FLUORESCENT-LIGHT-2ft-CFL_W0QQitemZ270383854188QQcmdZViewItemQQptZLH_DefaultDomain_0?hash=item3ef422326c&_trksid=p3286.c0.m14&_trkparms=72%3A570%7C66%3A2%7C65%3A12%7C39%3A1%7C240%3A1318%7C301%3A1%7C293%3A1%7C294%3A50 or would this 400 watt hps light system for like $150 be a better investment. I'm pretty much doing this for my own personal use. They both sound good but really dont know that much about lights so any help would be nice

No question, get the 400 HPS.
