Like I said before, if you want to go cheap, i'd strongly suggest you buy the HID Flood lights and rewire it. Rewiring doesnt sound as hard as you think. Theres only 2 sets of wires (2 wires in each set) that you have to do, and just cut an extension cord, THAT SIMPLE! I just think its pointless to buy those premade units, and you could always go to your local army surplus store and buy an ammo can for less than $15 to put the ballast in.
