Need help picking a fog machine and what kind of liquid to buy

Im sorry to create another Fog thread, but i have been searching for days on the site and going through the threads and i just cant decide what to get and what kind of liquid, i dont need anything crazy, but i dont want anything weak and im wasting my money.
I seen the monoprice one 1200-Watt Fog Machine, i see some good reviews and some bad. What is the best liquid to use? I seen bog fog, and one called froggys i believe. Im not concerned about ground fog, im looking to spend under $100 on fog machine (if possible) but i dont have a problem spending more if needed. And how much liquid to i need to buy? If someone can just post what they use and the liquid they use, i just want to purchase something that is working for someone already so i dont regret what i buy. I hope someone can help me. Thank you very much! Im doing a boiler room in my front yard (nightmare on elm street) and im going to be freddy, so i want to make sure its good. thank you
below is a pic of my front yard to get an idea of what im working with as far as size of area i need fogged.
