I grew up in Southfield and I won't go near it now. Stay far away.
Farmington hills, West bloomfield, and Novi are very nice communities, and all very close to each other. But it'll be hard to find a nice house under 250k. Home prices are high in the neighborhoods where people actually want to live. You're treading on upper middle class and high class areas here. It's not uncommon to find million dollar homes in these areas.
Farmington (different from farmington hills) is probably more your price range. It bleeds into F. Hills but the home prices seem to be lower. It's more middle class from what I've seen but still decent and you don't have to worry about being mugged.
South Lyon, Brighton, Howell, are also nice cities. They have more of a small town feel but are pretty close to the bigger cities with easy freeway access. But again, the home prices are around the 200-300k range there unless you tread farther out into the country or settle for a small 2 bedroom ranch built in the fifties. Newer complexes with expensive houses are popping up all over and it won't be long before they start to rival Novi and Farmington Hills. In short, the folks with money are coming here too and they like their houses big.
Ann Arbor would be my pick but that might be too far away from Farmington for you, plus again, you've got the home price issue. They aren't cheap there either.
Plymouth is turning into a nice town and I think you should be able to find a reasonably priced house there. Not too far from F. Hills either. I haven't been down there in a few years though so who knows, I could be wrong.
Good luck, and if you want my honest opinon. Don't move here. The houses are too expensive, and it's too damn cold. Plus our enconomy sucks.
