If you are adamant and don't want to give laser a try for your arms, I would definitely recommend electrolysis, with a speedy thermolysis practioner. The great thing about electrolysis, is the selectivity factor. Since we work on one hair at a time anyway, we can select those thick, pigmented hairs only and pass over the the lighter, smaller hairs to give you that thinned out look. It certainly looks more natural than that waxy, manican look you get when you wax or shave.
Another thing I would like to pass on to you: I do have a couple electrolysis clients who had their arms lased who are very satisfied with the results. All looked good to me as far as skin condition and hair count afterwards. The only complaint they had was the expense of it all.
