A good idea would be to wait to buy your dream guitar, and learn on something within your budget first. So, again, try buying a cheap guitar - you can still play all your favourite Sum41 tunes on it [a sarcastic remark was originally here, but was later removed by the author], and when you get better at playing guitar, you'll still have enough money in the bank to buy what you really want, not something that you dreamed of 2 years ago, when your musical tastes were totally different.
Here are some questions for you: What is your budget? How old are you? How long have you been into "punk" music [sarcastic remark again removed]? Do you plan on taking lessons, or how will you learn guitar?
Perhaps the others have other questions for you, so that we can offer some more specific advice.
