I'm new to this forum too - but I just had a Warmoth neck professionally set up using a PLEK machine, which is where a computer scans the neck and motorized files and saws file down the rough edges of the frets and file down the nut slots (which are only starter cuts on the necks you buy) to extremely precise, smooth tolerances for a really comfortable, smooth playing feel. The machine files the nut slots and adjusts the action based on your preferred string gauge and action height. It's really expensive, and it's hard to find shops that have these machines, but Crossroads Guitar Shop in Falls Church VA has one. Their basic PLEK setup runs at $225.00.
