How Expensive is the Display Exchange on the Laptop?

Dear people,

I own two laptops that unfortunately have both displays broken. I would have to have one of the two displays replaced in order to continue writing on an important piece of work. I would like to get away as cheaply as possible. Would it be smarter to repair the slightly older, but higher-quality Hp laptop, or the only three-year-old, but less high-quality Toshiba laptop? What sum should I expect? And where would it be best? (live in Berlin, if you know good repair shops in the capital!)

For your tips I would be really extremely grateful.

My fuzzi needed for 85 EUR, but also goes by external screen, the work!

Thanks a lot!
