I have been using a Bostitch Brad gun for a while, and have no problems with it at all. Except for the fact that the recessed holes need to be addressed before finishing.
I am finishing 2 desks for my wife right now and am getting tired of filling, staining and sanding holes. I always use 1 3/8 brads and see that pin nailers do handle that size. I always glue the nail anyway, and then clamp overnight usually, so strength of the nail itself is not an issue.
Question.....which one would you recommend, and are there any intricacies about the tool that I should know about? Is it worth it?
