Detroit: choice of IFR airports?

From what I've read Detroit area airports get pretty mixed reviews, some
pretty negative for g/a and general level of service & facilities. Can
anyone recommend the Detroit area airports to fly in to, and warn of the
ones to avoid? (With instrument approaches/ILS preferred.)---for
single-engine piston a/c. Ability to provide hangar for a few nights for
less than king's ransom, and friendly (not necessarily fancy) line service
would be of interest too. I suppose Windsor might be an option but don't
fancy the cross-border hassles so much as US-side airport.

Thanks for any thoughts from those familiar.
