Sounds like you've made up your mind. If you really love it and can pay it off, why not? It should last you a while.
Sucks that your parents are that into your finances though. My parents would die if they knew how much a LV cost or basically a lot of things I buy cost BUT they have no clue. My dad looked at my dog's LV collar and went, "Oh, look at you!" (talking to the dog) "You have an Yves Saint Lauren collar." (pronounced very poorly) My parents have no clue about any kind of designer whatsoever.
