I'm hardly an authority but here is my opinion. You say you just want to maintain sharp razors, so if it was me here's how I would do it. You will need a finish hone and they come in several flavors. I'll go with less expensive up. First the peoples hone of indeterminate grit (chinese 12k). It's slow but can put a nice edge on a razor used properly. Next either the Shapton 16k or Naniwa 12k. I haven't tried the Naniwa so can't comment on its performance but I do have a Shapton 16k and it will put a very sharp edge on good steel. Going up in price are the thuringian stones which include the Escher stones. Some razors really love these stones and not only take a sharp edge,but a comfortable sharp edge. For about the same cost as an Escher stone(and on up in cost) you might be able to get a nice japanese hone and although I don't have one (yet) I hear they are as good as it gets. Along with some of these finishers you may get some benefit from a bench strop with Chrome Ox or diamond paste. Perhaps some of the honemiesters can give better info but that's my 2 cents worth.
