Fluval tends to be good quality for the price. The light that comes with those is probably going to need an upgrade if you want to keep stuff that needs higher light intensity. The AI blades fit those really well but I don't know if they are available. I run a lot of fluval stuff, always good value for the money.
I would say the best way for you to go is look for a used tank but I am in the US and don't know how robust that kind of thing is where you are.
Fluval evo is definitely worth the buy, mostly any AIO is great. If you can afford a bigger tank (maybe around 20 gallons) it is better to go slightly bigger because it’s a lot more stable.
