You know... I have a 30" machine currently, and I love my big squeegee for laminating and taping. I find myself wanting a laminator for longer run stuff... but overall I love the big squeegee. Even if I had a laminator for the longer run prints, I'd still stick with the big squeegee on everything else.
And when I say longer run, my space is limited, and I am limited to the length of my work table. Thats not to say I can't do 20 or 30 foot prints with the BS, but I feel as though I'd rather run it through a laminator than move the media the length of the table several times on a long print.
Overall though... I don't think I could live without the Big Squeegee now that I have used one! Other can comment on working with the BS on wider materials.
