Yes, the 540 machine is excellent. I can't imagine how we did without it, like a previous poster said. We run tons of vinyl through it. Running banners is as close to printing money as you can get. Get yourself a grommet machine, run 13oz material and bam! Instant money.
Had it 6 months or so. No issues yet. Hard working machine. You do have to load the proper ICC profiles, though. After that you're good to go.
