Which would be the better and cheaper option (not that either is actually cheap!) to have a TV that pops up from a built in cabinet or one that drops down from the ceiling? We have the space for either option and want to be able to completely conceal the TV in our new construction. We're not going to get a gigantic one...probably 42-48 inches max. Also how far will the drop down "lifts" drop the TV? I don't want to strain my neck to see the TV. Where is a good source to purchase such things?
