You can buy U1-3 cheap as a pdf. U1 is easily the best of the three. In any event, you can get them each for $3.

Agree completely with this with the the explicit inclusion of opening it up to DM's Guild (like was done with Eberron).Honestly dealing with Greyhawk is simply, give the job to Luke Gygax, do it as a PDF, low cost and low risk, and if it proves popular, do a Hardcover later. Like they did for Waycarer's Guide to Eberron written by Keith Baker. They have the basic recipe for this, just use it. Anything else is just hypothetical complications.
