Budget laptop with a good keyboard

I find that I hate the newer types of modern keyboard that come with laptops. They become flatter and often smaller, feel miserable especially with someone who has "sausage fingers".

I prefer the old mechanical-type keyboard with a longer ride, but it seems that notebook makers are running away from them unless they want to buy a super expensive gaming machine.

Has anyone ever seen such a laptop with correct specifications for editing photos, vector work and especially a nice keyboard?

Do not want to spend more than £ 500 / € 500 ish. A big challenge maybe?

I was looking for Lenovo Thinkpads older and refurbished, Amazon has one that has been refurbished for 350 and the keyboard is perfect.

Thank you
