I need advice on a good board

i started boarding this summer. i was getting a little frustrated but then i landed a W2W and now im hooked and i want to do everything. im looking to buy my own board and i have no idea where to even start. what is the difference between nose design, fin amt. and placement.etc...i am looking for something that is good for beginners but one that will last a little while into my advancement so i dont feel like i will need a new board next summer. any advice will be very appreciated.
