wrt bufferbloat: my internet is too fast (150 mbps) for a cheap router to effectively manage the connection, meaning that unless i pay 250€ for a router, I will just slow down my Internet needlessly.
The Netgear R7800, while a bit more expensive ($150), is still cheaper than the price you mention, and is very powerful and able to handle gigabit speeds easily.
Guess your customs are not equal 80-90%.
They cost about $100
Edit: wups, misremembered Serbia as Slovenia. More like 160 Euro in Serbia: http://www.sampro.rs/Proizvod.aspx?kid=162&pid=33332&name=Mi...
Edit2: Arrgh, and didn't read far enough on the thread before sticking my foot in it where you otherwise discuss the Mikrotiks.
(previously) Going up to the question of Slovenia higher in the thread, there's a Slovenian vendor who has the "hAP ac" (dual band, gigabit, SFP, USB port) for 121 Euro (https://www.virtua-it.si/izdelek/mikrotik-routerboard-hap-ac...) along with other less-capable and cheaper models.
edit: forgot to mention, it's 60€ brand new from a friend who works at a WISP
