How to retrieve data from SSD (MacBook air 13 inch 2014)

Hi, I spilt some water on my macbook air 13" early 2014 and would love to retrieve my data from the SSD. I've seen that people recommended "OWC Envoy Pro". but being a broke uni student, I was browsing through ebay and stumbled across few SSD adapters that were a lot cheaper. I'm not too familiar with electronics & technology so could anyone please recommend me a correct adaptor to transfer my data from old SSD to new mac book (or external hard drive)? or an alternative method would be great as well.

my current macbook is MacBookAir6,2 (13") MD760LL/B early 2014.

Thank you sooo much in advance,
