For €200, have a look at the manual focus options out there. Nikon made a few 55mm macros. that should be in that range. Also, if cult-status hasn’t driven them through the roof, have a look at the old manual focus 90mm f2.8 macros (I think). Manual focus is fine for macro, and you’ll find yourself manually focussing more than you’ll be using autofocus. If you’re trying to get an autofocus macro lens for less than 200 you’ll have your work cut out for you, but €275’ish will land you a Tokina 100mm f2.8/ Sigma 105mm f2.8 used, and €350ish will give you options new.
