Recommend Loupes?

Current first year derm. Did my first excision today! (with lots of guidance from upper level).

Do you think loupes are helpful during residency? I'm not sure what I want to do after residency (most likely not Mohs but who knows?), but I want to train the best that I can, and if they will help me improve my surgical technique a little bit, then I'm willing to spend on them (have been saving a lot since med school graduation). Thoughts?

Thanks!
