TC Dave gets my vote -- and my $$ when I have any... ;D
He is reasonably priced (better than any other pricing I have found) and does remarkable work. Plus, his turnaround time is short.
I've been enjoying his forends for a while, but recently I got a complete stock set from another cusom maker. And while the fit and finish were perfect, the forend did not suit me to a tee, so to speak.
One PM to Dave took care of everything: He was able to match the somewhat exotic wood, fashion a forend that I was comfortable with and do so for a very reasonable fee.
