I big thank you from you all, i know im a novice but iu have a machine to start me off, and now i know the make, the model and the psi from all your help, just need experiance and some further training and bobs ya uncle, I think at my level a 7opsi is a good power to learn on, then when i get better i will apreatate the power of the bigger machines and be able to do jobs quicker but for now i am just practicing and in no rush, id rather take my time and learn the ropes slowly.
