Hm. Looking things over...
The Iwata Eclipse has the nozzle type you want... but not the preset handle (there is such a handle for the Eclipse, but it must be bought separately, and isn't cheap). It can be had for similar price to the Silverline if you buy the
direct import version, though that's not taking shipping into consideration, so actually an indeterminate amount more expensive. As much as I personally like the Eclipse, it does not compare favorably in terms of cost vs. features on the German/European market. For the same money, you're better off with the Evo Silverline.
At the very tippy-top of your budget is the
Olympus MP-200C at 18360 JPY, (about 144 Euro as of this writing). That's the Olympus equivalent of an Iwata Custom Micron C, so a VERY good deal if you can swing it. Free shipping, but that can't speak for local customs or taxes, of course. Doesn't have the type of nozzle you want, but considering it's held as the equal if not slight better to the Iwata Micron (fewer bell and whistles, but allegedly sprays a tad nicer), that's like turning down a Ferrari 'cause it doesn't have the transmission you want.
H&S Evolution Silverline has all the features you want, plus easy future upgrade/customization potential, and probably cheapest parts since it's made locally. Only downside is base price is on the upper end of your budget.
Ordinary non-Silverline H&S Evolution is only a couple Euro cheaper than the silverline. What you get for that tiny price difference is significant (including, but not limited to, one of your desired features). If you can afford a regular Evo, you can afford a Silverline instead, so the regular Evo only merits token mention.
Hansa airbrush has all the features you want, and is approximately similar price to the Evo Silverline. Two stage trigger is a possible pro, depending on preference. Con is it's not upgradable or customizable like the Evo. The Hansa is interesting, but like the Eclipse, falls short of the Silverline in what you get for your Euro (though by a lesser margin).
Iwata Neo has only one of the features you're looking for. Also is not technically Iwata, as Neo manufacturing is outsourced to Chinese factories rather than made in Iwata's own factories. It'll be better than your Fengda, but not as good as the others on the list. It's cheaper than an Evo or Hansa...but that's about it. It has basically no advantages save cheapness.
H&S Ultra has only one of your desired features (floating nozzle design), though by buying an extra nozzle cover separately, it can be converted to have two. Pro is it's cheaper than a Neo... but only if you don't buy the extra nozzle part for the extra feature you want. Con is it's not as upgradable or customizable as the Evo.
All things considered, it still looks like the Evolution Silverline gets you the most bang for your budget, with the Olympus coming in second. Oympus is probably the better brush in terms of raw performance, but the Evo has everything you want right out of the box, and will have more Jack-of-all-trades adaptability.
