Yes, Derek Cohen does not take short cuts.
Two came to my mind, who could do both, fixing mistakes and producing perfect or close to perfect results: Tage Frid (whose DVD, using power tools, is not online) and Paul Sellers (free subscribers can see certain of his masterclass clips).
Another, forgot his name, a retired editor from Fine Woodworking, shows how to do cabinet doors. Not a long clip but he shows step-by-step and the finished doors are what you could expect to see from people like the two Davids (Charlesworth and Savage). I am inspired only by the works of those -- amateurs or not -- who know their stuff. Crude work or techniques are not my taste. (Edit: Life is too short in my shop for any of those.)
Anyone who likes to be inspired differently, be my guest.
