I know you are looking to save money, but a hot laminator is a very good investment. Much quicker and consistent than using a clothes iron. I made the switch, same time I started using Pulsar paper, and have only experimented a few times with other papers a few times since. A laminator takes away the guess work you have with the iron, where you have temperature, pressure, and time to deal with. It's more a matter of preference I suppose, some people are thrilled with the skills of using a clothes iron. I just want the board, with minimal hassles, don't even like hand drilling the holes. If I saw a cheap CNC drilling machine, I buy it.
Is some tips for using an iron, from the Pulsar site. They don't sell overseas, but might help you get better results. They want you to have good excellent results, and spent a lot of time working to make it easy. There are a lot of sites you can get a how-to, but this one is great.
