I've seen a lot of discussion about using a graphics tablet for photoshop editing. One of the main reasons for looking is due to the stress on your wrist and hand whilst editing, I get a bit of trouble with my hand accordingly. From the people who use them - is it worthwhile getting a graphics tablet for photo touchup? If so, which one for a beginner, Wacom seem to be the best but there are well regarded brands which are cheaper such as Huion. Thoughts/recommendations/feedback? Constructive only please.
