Re: Moving to Dayton...
Back when I was looking at places to move to last summer, I found a couple of fairly inexpensive places out in Beavercreek. I remember finding a sweet apartment for just under $500 a month out there, but I wanted something a little closer to UD, since I was starting grad school. West Carrollton may also fit your needs, since you can probably find a cheap place and it's close to 75 and downtown.
Of course, you could probably get a place in downtown Dayton, or the Centerville/Kettering/Oakwood area and I'm sure it will still be significantly cheaper than Brooklyn.
