This is a helpful video on budget espresso. The Gaggia Classic/Iberital MC2 combo is a popular one for those on a budget. The main limitation is that the MC2 isn't really adjustable between grinding for filter and grinding for espresso (you can adjust between the two, it just takes a VERY long time).
Others will likely remember better than my tired mind the best options for a £200 grinder.

400 ISH maybe all in (ideally less but don't wanna buy anything again in a few years)
