Oh, highly recommended! I didn't realize you were asking for yourself. If I'm looking at it right you're probably looking at a couple of hours work for your first time (that includes time rewatching a video of someone else doing it to make sure you've got it right). Someone that's done it a few times could probably knock it out in under half an hour if they don't want to change the strings. I'm pretty careful with my work so the last time I did a swap it probably took me 45 minutes from grabbing my tool bag to tightening the strings back up.
