That would depend on where you're located, as not every brand is equally available in all markets.
But given you're in the EU, I'd say the
Ersa i-Con Nano (much better performer than the RDS80 as it uses newer tech). Tips are high quality and inexpensive as well.
A bit over your stated budget, but worth a serious look, would be the
JBC BT-2BWA (Weidinger Edition) that's currently available for 259.95EUR before VAT. This is the least expensive JBC station available, and is specific to Weidinger. Any other JBC will be notably more expensive, save perhaps the used market. Please note the tips are cartridge types, so they're more expensive than those used in the Ersa.
Both brands offer a wide selection on tip shapes & sizes, so you're good there. Distribution for both brands in the EU is decent as well, so you're not limited to a single source for consumables & spares.
