IMHO for what it's worth. I would seek counsel that specializes in firearm related issues. When you have a specific need (Setting up NFA trust, appealing a denial, criminal defense, etc.) find a lawyer with expertise in that area.
It also usually helps if at all possible he practices in the area local to where you live or where your court appearance will be. He will be connected to other officials/judges/lawyers that may benefit your needs.
In most instances the old adage "you get what you pay for" is true. Put a few dollars away should the need ever arise and I believe you will be better served.
