Where can I find a replacement 2DS or can it still be fixed?

So it happened that while I was on holiday I dropped my 2DS in a lake. After 5 mins of fishing it out we had this brilliant idea to put it in a bag of salt (turns out we were supposed to use something else). So now I have this salty, soaked 2DS a day after the incident. We are trying to fix it however I believe it isn't repairable. We managed to recover the SD card and possibly the game, however I do not know where I can buy a replacement without having to pay for a bundle with a game I won't be able to use because I will swap the SD card out... So where can I? Or can I still repair it?
