Thought I would revisit this topic now that many new kits are hitting the vendor shelves. Also with the addition of the new click mechanism that most are going to. So what is the best click pen on the current market that you recommend?? Why and are there negatives to it?? heard about this little piece that seems easy to lose if a customer changes the refill. Maybe a photo showing what the kit looks like. I am still in search of a good clicker. Thanks.
