My backup iron is a Proctor Silex, which I loved until I dropped it and the button for steam stopped working. I can still use it, just have to have a water bottle nearby to spritz whatever I'm working on. My newest one is a Black and Decker, this thing is a workhorse and for under $20, I'd say it's a good find. Then I have a Clover mini-iron that helps me split my seams open and is a great alternative to finger pressing.
I've never been brand specific when it comes to irons, Proctor Silex seems to be my go-to but if I find an iron that I like, I grab it. I do like the way the newer mini-irons have been looking, waiting for them to go down in price since they're so new. I'd love to have a cordless iron!
