I broke down and ordered an ATG. I hope I like it, and won't have trouble learning to use it. I hated to spend the $, but the adhesive tape for it is so much cheaper than buying individual tape runners or disposable dispensers. I'm using a 900" roll of double sided Scotch tape with my tape dispenser I have now. It works pretty good. When I get the other regular tape dispenser, I am going to put my roll of Magic tape on it, and that way both my double-sided and magic tape will have their own dispensers. I love using Magic tape to hold my paper still when I am using rubons or embossing. Saw the way some of the users on YouTube decorated their ATG's; so cute! Maybe I can use some of my leftover blocks from stamps I unblocked to make me an ATG holder.
If I don't have trouble learning to use it, it will definately help on all the larger pieces of paper that get glued down; that takes a ton of adhesive.
