It is worth hanging on for the Amazon Black Friday deals. They often have older models at significant discounts from all the brands.Yea, the modern DSLRs are not cheap. A used Canon 80D would be a great choice, but even that would likely still be £500+.
My daughter bought a Sony A7 a couple of years ago for a very low price (less than £500 I seem to recall), including the quite acceptable kit lens. It is three models old now but produces fantastic images
