wasn't expecting this much feedback thanks guys you rock

i'll definitely look into all the basses and sites mentioned
and just for the sake of more information here's the deal
I'm saving up for my drivers license/car, hence the small budget for the bass but I'm pretty committed to learn it, I don't think a cheaper bass will throw me off, I will have more money to throw around at the end of the summer but I just can't wait to get one even if it's cheap and has no resell value maybe it's dumb but I'm too eager to wait

... I still have my first classical guitar which was like 30€ at the supermarket about 7 years ago, I kind of get attached to new stuff even if it's cheap it's always the start of something
My brother also used to play bass and he moved to England leaving his amp and speaker behind which is perfect for a poor pleb like me, he had a cheap yamaha that got a set up and sounded pretty great, he always told me that a 200€ instrument could sound like a million bucks in the right hands so having a cheap bass was no reason to quit which also motivated me (even tho I was more into guitar at that time) seeing him practice so many hours with a "crappy" bass/amp was inspiring.
I never had lessons or followed daily exercises while playing the guitar, I would just sit in front of the computer and learn random things for fun, nothing too serious but I think it's about time I really learn an instrument and I've always had a secret crush on basses so I'm going for it
edit: self making the set up is out of question, I'm a complete noob and want a proper job at least for the first bass, after that I'm willing to learn how to do it by myself
and about squiers, even a used affinity series which I hear are not worth it at all is about the same price as this SX new or maybe I'm not digging hard enough (?) the sx would be a total of 159€ (around 138 pounds / 170 usd)
anyway I'll keep searching, only get paid at the end of the month either way
