Interesting comment Roger - I have the two heat model #1701987 from Mybinding (Ebay seller) that "seems" to be the same as the one from Pulsar - can you confirm the Pulsar is the 1701987 model?
I also have one of the single heat versions currently sold by Mybinding - I've not even taken it from box. I purchased it as a spare thinking it was the same as the 2 heat model 1987 I had. Ooops - I should have checked closer before purchasing. I do think it will handle 300F heat, and I do use an external controller that I homebrewed using an ATmega168 chip. I do TT around 310ºF and am very pleased with the results.
One of these days I do need to drag the new laminator out and test it.
