Wanting to invest in an air fryer but have no idea what one is the best

I’m needing a bit of help, I’m wanting to invest in an air fryer but have no idea what one is the best🤔. It’s just me and my son at home until my partner is home so I’m also not sure about the sizes and what’s a good size for 2/3 people? I don’t have a huge budget either so something not overly crazy priced. My oven takes double the amount of time to even cook chips (literally takes 40/45 minutes for frozen chips).

Any help please🙏🏻

I’ve attached a photo of the spaghetti and meatballs I made for tea last night because hob meals and the easiest things to cook and was also incredibly cheap to make:

IKEA meatballs £5.95 (I only used about 12 so probably about 90p)
Asda spaghetti 23p
Asda tinned tomatoes 32p
Stock cubes
Herbs
Garlic

So in all easily cost less than £1.50 for 2 good sized portions and leftovers🍝
