The noise from having a router and vacuum dust-collection running all the time can become a problem in residential areas. Most would like a full-sized machine that could directly handle standard sheets of material, but the space is not the only limiting factor (i.e. the insurance provider could pull something nasty with your mortgage creditors etc.)
Peoples situations will differ, and definitely check out reverse-spiral flute carbide-cutters if you handle a lot of sheet-work on a 2.5D setup =3
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.
