Our walmart had some laminating machines for about the same price. But I picked one up and it was super duper light weight compared to the machine I use at church (heavy!). I wonder if the heated drums are substantial enough to do a good job for multiple sheets.
Then I noticed that it said to use their laminating pouches only, and those were super pricey compared to going to Sams. So, I will continue to use the machine I have access to.
However, Amazon has the Royal sovereign laminator for $20
Amazon.com: Royal Sovereign 9-Inch Laminator (CS-923): Office Products
and that's the brand of pouches I buy at sams. I would check to make sure that the maximum thickness of pouch that a machine can do (it's in mils...like 3 mil or 5 mil) is compatible with your pouch choice.
