Someone needs to start a business selling print-at-home furniture/home-improvement plans that include parts lists (and, ideally, costs) from their local Lowes / Home Depot / TrueValue / Ace / etc.
Most folks who want to tackle small projects don’t want to buy books or magazines that may (or may not) include what they’re interested in – but which will definitely include loads of stuff they’re not.
Having a simple webstore that offered complete build instructions, parts lists, and approximate costs (both dollars and time) would be awesome.
I’m thinking something like an on-demand version of eMeals, but for your workshop.
