Joolz, by what I've seen of your model building abilities, I would of thought doing the PE would'nt be a problem for you. The only thing in the way of magnifiers I've got is one of those stands with a small magnifing glass an some croc clips to hold items in, that you are able to move around to different positions, think its called extra hands or something like that, I got it from hobbycraft stores. I also had my reading glasses on which I do when modelling anyway because of the small parts. I have a large handheld magnifing glass as well but it is a much use as a chocolate ashtray to be honest. If I had some spare cash I think I would purchase one of those headworn magnifiers I think Graham mentioned it in one of his posts. Good luck with it mate.
