The only suggestion I have is to check Craigslist often. When a decent Van comes up they get snapped up quickly so you need to be ready to go see it, evaluate and then buy. Not always possible but as I said the better ones and even the not so good one's get snatched up quick.
You might consider something along the lines of a Honda Pilot. A very decent vehicle and known to be fairly reliable. Craiglist shows a private owner 2007 in Martins Ferry.
Best of luck to you.
