While everyone wants a machine for full-sheets of plywood, they're expensive, and not used for many projects --- a smaller machine suits most needs and there is always tiling.
My machine is quieter than my neighbor's drum kit --- and I've run mine after 11PM and you can't hear it over traffic and the nearby speedway (on race night) outside in the yard (a quiet vacuum helps a lot), but I have gone over to their house at 11:01 PM to remind them of what time it is.
