easiest free or worth paying for ip masking program

[spfd]

im looking into masking my ip, umm pretty much

just looking for a really easy to use program

but if any of you guys know a program worth paying for, sure ill go for that i guess

anyways, someone let me know, ive tryed a few already
i found surfanonymous the easiest to use but the gui on that program looks like it was made by a 10 year old =p
