RE: is there a difference between irons?
An iron is an iron. There can be a temperature difference from iron to iron too and you can't go by what the true temp is by the little dial, you get used to the iron you have over time and use. My old iron gave up the ghost and I still haven't gotten used to my new one. I use the heck out of my trim iron too but it's not a must have item. They come in handy though.
