Some things that you guys are mentioning are DONATED to the church by people, i.e. it doesn't cost the church a penny for it.

I know this to be true because at my church they have a beautiful stained glass mural behind the choir that was donated by one of it's members. He asked for that specific thing to be done because he wanted people to see something pretty at church. It cost him some money, but it didn't cost the church a dime. Things like that are more common than you think.

The other night, speaking of mega sound systems, I personally had to bring a cd player to play the music for the kids because the old cd player died. I left it up there and it will probably become a permanent part of the sanctuary where we meet for the kids music time. That didn't cost the church a dime either.

There are many other examples from swing sets to pinestraw. It doesn't happen everyday, but sometimes one time donations can last a long time too.

You'd be surprised at what a good church's budget consists of. It's not always to buy their preacher a MB or a mega mansion. Again, that is the exception and not the rule.
