passche VL-set or the iwate hp-c have both and they work great the iwata has the capability of finer lines provided you can keep your hand steady enough to do it, the VL is fully capable just takes a bit more to clean then the HP-c but can do fine lines as well as full body coverage that the HP-c just can't do as quickly and if your working with candies or transparent paints then the VL makes it easier for a novice to get better results due to the larger coverage area per pass then the iwata.
I own both and use them in the areas that they excel in but if you are going to get one and are not sure if you plan to stick with it or you just want to learn then I reccomend you get the VL the parts are much cheaper and it is just more forgiving then the iwata, the iwata needles can be damaged very easily if your not careful.
