The issue with refurbished ones is guaranteeing quality.
If you buy from Amazon Renewed, for example, you have no idea exactly what you'll get. You could get a pristine unit without a scratch on it with a battery that has barely 10 cycles, or you could get a well worn (with plenty of micro scratches and minor nicks) with a battery that's been cycled 500+ times. It's kind of a crap-shoot when it comes to buying refurbished.
As someone who takes pride in keeping my phones absolutely perfect and even micro-scratch free, it's too much of a risk.
I bought mine on backmarket, they act as a middleman. You buy from a repair with a minimum six months guarantee or beyond. If it stops working, you can send it to repair. Batteries are guaranted to be at least 70% original capacity or have been replaced. There are different grades from scratched to pristine. Not sure they operate in your country though.
Getting a former flagship phone for 150 euros with a CPU just as good or equivalent to a new phone of the same price seems worth it to me. Plus it's nice not to have to worry about that expensive thing in your pocket.
