Good deal heavensabvus1! That is something needed to be taken into consideration after bulbs shipping etc. is it really going to be much less.... For me it was I just got the simple 15 dollar kit to upgrade my lighting a bit for some non - CO2 tanks.
But seeming how you are going towards the Current fixture I will add in that I have one on my 75 gallon. I have had it for about a year and a half now, and I love it... it has worked great and has been a quality fixture for me, and the moon lights are a nice added bonus, espically if you plecos or anything.... however mine did burn out or the transformer went bad Im not sure..... but other than that I would definantly buy another!
