That's precisely what I'm looking for. When I run a pre-made adventure it's because I don't have time to build a custom one. I'd like to be able to read the module, pull the map into MapTool place the mob tokens and be ready to go. In situations where I am not running a game at home I'd like to be able to print out the map and take it with me (or buy a print version).
To my mind, providing high quality digital versions of all the maps in a module is a no brainer, even at a slightly higher cost. They *must* have the maps in a digital form already.
For something like Sellswords of Punjar I can scan the provided map in, but most modules don't have that option, plus it is more work. The encounter in the first issue of Level Up is another example. Duplicating that map isn't beyond my (limited) cartography abilities, but I'm unlikely to spend the time. IMO that map could be provided with the pdf version of the magazine (particularly since print purchasers get the pdf for free) but I'd probably pay for that as well if needed.
In an ideal world I could buy a DCC, go to the product page on Goodman's site and download jpegs of the map for every encounter in that module. Failing that I could go to RPGNow and buy every map for that product in a pack for a couple of bucks. Obviously this would apply to any adventure publisher, I just happen to bias toward GG.
