You may want to consider having one built before committing to a kit. Not that they are necessarily inferior, (most all of the commercial WFO's are commercially build) just a better value-plus the personal attributes-IMHO.
Either way, they are worth it. So much so you may find yourself selling the kit unit after the first year and having one built.
