Regarding a few comments about having no love for sheetrock on basement ceilings. One REALLY good reason to hate it is that most create a huge number of code violations. The reason is access. EVERYTHING that needs any potential service or repair, and is covered by drywall, must have an access panel. This included electrical junction boxes, plumbing valves, HVAC duct dampers, motorized dampers, tub drains, sewer cleanouts, and so on. Legitimate access hatches are expensive, look terrible, and are rarely used in residential construction. So, when your shopping for a used house, with a finished basement, and you look at a sheetrocked ceiling, ask yourself, should it be one continuous plane of unbroken sheetrock, and how many important things did the homeowner cover up? (When he did the job without permits, LOL)
