>>6419073Paint, brushes, tools and glue is a bit of an investment when you're starting, but don't pin your hopes all too much on those gift/starter sets with paints included. It seems they have a worrying tendency not to come with all the paints you need for one thing, and I'm not sure the tiny little pots of we're not entirely sure what will serve you all that well either. If you get glue in a tube you most definitely ant to get something else, an extra thin cement (Tamiya or Mr Hobby) or a regular one in a bottle with a needle tip (Revell Contacta Professional for example), ideally both. Whatever brush is included is highly unlikely to get you anywhere on its own.
The big, underlying problem of course being that poor tools (paint, etc) can end up discouraging you by making shit harder than it needs to. But as you've noticed, the good shit ain't cheap when you need to buy all the basics all in one go.
Now if you must,
https://www.scalemates.com/kits/100369-airfix-a55102-mitsubishi-a6m2b-zero should have a decent kit in there and be about as cheap as it gets for something like this. You'll need to toss in the main fuselage colour yourself though (a single one at least, try to find a warm grey-beige, somethign in the vicinity of this pic) by the looks of it, some new glue, more brushes, plus a hobby knife or whatever else will be used to get the parts off the sprues.
Also available as just the kit itself:
