CNCs are no different than any other machinery or business decision... "application, application, application". A CNC is "another worker" for your shop so it's important that the "new worker" has the skill set and capabilities that will "pay for their salary". 5x10 is a really good size for maximum versatility for sure. It can cut BB, "long things" and so forth while also being able to do small jobs, too. I'm not personally a fan of tiling for business use, but do agree it can be valuable for the more casual user, so the longer machine again, makes sense. Other companies to look at that are within driving distance of you are Camaster and ShopSabre; made in USA machines with heavy welded construction.
