The edgerouter lite is quite old at this point and if the purpose is to use QoS to manage buffer bloat then the EdgeRouter X which is only like $50 would be faster. The edgerouter lite is of limited use for new installations nowadays.

will do, that and mikrotik. i think i can manage managing it fine, i've worked a small bit with mikrotik

For that matter, it looks like most of the Mikrotik routers can actually have OpenWRT installed on them, though not all of them have device-specific pages in https://openwrt.org/toh/views/toh_available_864?dataflt%5BBr...

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.

Netgate makes some very nice appliances. For example:
