H&S Evolution Silverline Duo is what I've used.
0.2 & 0.4 needles, small & large paint cups, built to last and fully adjustable. Can take solvents without disintegrating, spares relatively inexpensive. Very smooth & reliable, hardly ever gums up - and that's usually my fault for under-thinning the paint.
Not the cheapest, nor the most expensive, but will last for many years.
I've got a second hand Iawata HP-BH at 0.2mm, so I tend to use that for detail work, with the 0.40mm needle on the H&S.
