My M1 MacBook Pro 2021 has water damage

Good day, I’ve just received a quote from the Istore for 1880usd to repair my 2021 Max M1 MacBook Pro which my son spilt water onto, they state the following.There is damage resulting from liquid contact in the main logic board that is not covered by Apple’s Limited Warranty, an AppleCare plan, consumer law, or the original quoted cost of the repair.
Is it a reasonable quote. Or can I get it fixed at a cheaper price elsewhere, kind regards Paul
