New iPads start at around $300(or £/€ since regional pricing is just the unit of account change these days) directly from Apple and at around $200 for a officially refurbished 1-2 year old device.
If I was looking for a £200 tablet I would get a refurbished 9.7” (2018/2017) iPad of Amazon. The 10” 2021 iPad is/was on sale on Amazon for £320 and that’s probably the best bang for buck you can get as far as tablets go these days unless you really need a large onboard storage. And that’s a brand new device.
