Sticker shock on halides is easy to fix. Build a canopy and get a retrofit kit for halides. under 400 for icecap ballasts, sockets, reflectors and cords. With a 75 just get a 30x14widex16tall sump, a asm or euro reef skimmer rated for at least twice your tank volume, a tunze stream or drill the tank for a closed loop, a good return pump and a heater. Its really pretty simple if you dont do every thing the hard way like I did and end up buying lots of junk then getting the good stuff. LOL
