I'm currently looking at buying a house. I'm having a tough time finding the just the right size house that has a nice room for my system. There are only two of us so we don't want a big house. I have a nice sized room now, but we are looking to get something all on one level. Currently we have been looking in the neighborhood of 1800 Sq. Ft. How many square feet do you have? What obstacles did you have to overcome?
