I've used Richards, GAG, Boyds and Willig. All higher grade walnut, said to be 95% inletted. Some pain associated with each of them. Voids, bad grain pattern, cut-off cheek piece from use of a too-small blank and so on. For me, Willig was fastest and most accurate, and would do palm swell, cast off and so on, with my own wood.
At the risk of sounding reactionary, I'm at the point where I've bought a used copy of Alvin Linden's "Stockmaking", the necessary gouges, planes and chisels, blanks from Luxus, Goby, and Chiron from on-line double-sided photos, and started hacking.
