I got a great travel iron at Walgreen's for $10.
It heats up quickly, is lightweight, steams, and has several heat settings.
It's bigger than the mini-iron, but not as big as a regular iron. It's big enough that it fits completely over most of the squares I'm making.
Just big enough for my individual squares that I don't have to move it around to steam the entire piece.
Pefect size for pressing while sitting at the sewing machine. Enough heft to do a good job but light enough that it doesn't hurt my back to lift while sitting.
