I think that the laser is a far better way to produce parts for model aircraft. The laser's narrow kerf and efficient use of material will more that recoup the cost of investment over the lifetime of the tube. There are many relatively inexpensive programs to layout "nests of parts" to minimize material loss and with the laser's relatively small perk .005 or less if set up properly even on square corners there is no need for cleanup like there always is with a CNC router. The diameter of the router bit becomes a radius that must be removed on every square corner like rib to spar joints. The new laser software even allow multi passing to cut thicker materials. I was involved in the industrial laser cutter manufacturing business for 30 years so that is where my vote goes.
