There will be lots to choose between them. I only know the Airfix and Matchbox ones, but you can be sure some of those kits are easier to assemble and/or more accurate than others. The Hobby Boss kits are in their easy-assembly line, which will give you a kit that’s both cheap and quick to build, but looks good anyway — if you don’t mind cockpit detail that’s only slightly better than 1960s standard.
Thanks for your reply
I've done a bit of Surfing and watching YouTube videos, and asked the same question on a Facebook Group
There are several kits available in the £8 to £10 range, and I've just ordered an Eduard FW 190 A-8 Weekend kit from the Scale Model Shop at the top of the page
