I don't have a sharpmaker but I do use the Spyderco stones. Like Chuck said if you use the 40 deg setting you should be able to keep the Delica sharp. You probably won't need to worry about it for a while though. It will come sharp.
However, if you own ZDP you should get something coarser than the medium Sharpmaker stones. Since you are getting the Shaprmaker I'd recommend you get the diamond stones now if you can. If not, you can wait but I think you will want them sooner or later. In fact I think you will want them anyway for all knives. They will save a ton of time whenever you need to reprofile (change edge angle) the edge on a knife.
Welcome to the forum and congratulations on your choice. I know you will love the Delica.
Are you getting the FFG Delica? Better make sure. There are still some saber grind Delicas available. They are nice but you don't want to get one if you are wanting the FFG knife.
