If you are able to get 3 to 5 months out of a razor and have 3 or 4 razors in your rotation, the cost to have them professionally honed will save you a lot of money and frustration from buying honing stones.
While this is a statement that is quite counter intuitive for a site dedicated to hones, I would like to strongly second what Ray said. Learning to strop properly is imperative. http://www.coticule.be/stropping-a-straight-razor.html is a rather perfect summary of what you need to do. I was having the same problem, ie razor went dull after about 10 shaves. Then Bart taught me a very simple lesson: 'Do not flip your wrist, flip the razor.' Previously, I was doing 50/50%, and that was the problem.
And yes, I believe that for most people - especially those with two left hands like me, or those who are interested in shaving but not necessarily restoration - being able to maintain a razor is sufficient. Commercial honing can - but need not necessarily - cost some money. Given that you can get by with one razor for a very long time if you maintain it on a Coticule (which you already own), learning the techniques used to restore razors is not a requirement.
I know that in other forums you are considered an incompetent loser if you do not own a barrage of hones and have restored thousands of razors!!!!!!1 Incidentally, the quality of entire lines of razors is measured by 'how easy they are on the hones.' Poppycock. Marketing drivel by people making a living honing other people's razors. Incidentally, though, the reason why the otherwise rather unimpressive DublDuck razors (cheap German export stuff for the American market, you remember?) are fetching the insane prices they currently do.
So, go through the documentation again, make sure you understand how the Coticule works at various stages of dilution of its slurry, and maybe(!) check whether your stropping technique is really perfect. Because if it is not, you will be buying finishing hones until hell freezes over without any improvements in your shaves.
