Heard good things about the Amazon Basics one, well as far as I understand linky > https://www.amazon.co.uk/AmazonBasics-Electronic-Flash-DSLR-Cameras/dp/B01I09WHLW
Would be handy to know whether you need TTL or if you are happy with manual flash.
Otherwise my recommendations would be -
Yongnuo YN685 if you want TTL
Yongnuo YN560 IV if you want manual
This if you just want a single flashgun; or if you think you might like to be looking at off camera flash, multiple speedlights or studio / portable flashes then jump straight into the Godox range - the V860ii with lithium ion battery or TT865 for the slightly cheaper version with AA batteries.Would be handy to know whether you need TTL or if you are happy with manual flash.

Rebadged versions of the Godox flashes are available from Lencata and others with U.K. warranty.
