SignCraft was (and still is, in a much more limited way) a great resource for sign artists and crafters. Times, however, have indeed changed, and for most of us signs are now a production commodity. There are still opportunities for creative expression in sign design and sign building (resort areas, gentrified downtowns, corporate identification and branding programs), but the opportunities are limited and usually only the best of the best get those jobs.
In addition, sign opportunities have been drastically curtailed by a trend to buy stuff online and a larger share of advertising budgets going to the internet. Small specialty retailers have replaced brick and mortar with Amazon and Etsy. There are opportunities out there for sign artists and crafters, but they are becoming scarce. The industry is continuing to shift to corporate owned chains buying signs made in factories, with the biggest opportunities for sign shops being installation and maintenance.
SignCraft was an inspiration to me in my early days, but now it is a trip down memory lane. Still showcasing great work and talented sign artists (albeit in a digital format these days as it too has become a victim of commoditization and the internet). I would say that their pricing guide may be relevant for those still handcrafting signs in resort areas and for specialty retailers and independent restaurants, but for most of us the pricing is out of whack with current conditions.
