you'll learn like most of us, it's less about budget and more about value for money! please don't think paying MORE is going to get you a better experience.. a WL who can't do it at $300 isn't suddenly going to be a porn star at $600...
You'll find yourself spending under your budget actually and I advise you to use that left over money to try different experiences... as a newbie I used to exclusively use escorts&babes and scarletblue... LOL... yes I know, what a nuffie! but at least I didn't make the same mistake twice! WHEEW!
