Edu, I was in the same boat about a year ago. I bought a monthly license with photoshop (and later sketchup for 3d areas) and started making my own. It's a pretty even learning curve, but I found I preferred making what I needed for the night's encounters rather than relying on the marketplace which ~might~ have something I need but probably not for multiple encounters. Given that I was spending more than the 10 bucks a month on purchased map content, the photoshop license ended up being cheaper. I started out with pretty much crap and now make things like these: <a href="https://db.tt/6NxbyLEV" rel="nofollow">https://db.tt/6NxbyLEV</a> <a href="https://db.tt/oZetExyl" rel="nofollow">https://db.tt/oZetExyl</a> <a href="https://db.tt/SwC9KXSc" rel="nofollow">https://db.tt/SwC9KXSc</a> <a href="https://db.tt/yIEsuemK" rel="nofollow">https://db.tt/yIEsuemK</a> It all depends on your skill and knowledge with the software, though. If you haven't learned photoshop previously and don't have a few weeks to play around learning it via trial and error you probably want to stick with premade content. If you do go photoshop, stick with looking into layer textures and layer style options. Most of the basic stuff needed to make maps walls, trees (et al) can be found simply by using combinations of the bevel and emboss sliders, choosing the right textures, and poking around with a nice assortment of brushes and such.
