Should I buy??

Yesterday i passed by a nikon camera fair in mid valley, many ppl holding their dslr to capture the beauty of the models on the stage. I really admire them and this inspired and attracted me to buy. However, my photography skill is juz normal, shud i buy a dslr and learn myself? I hope it is not a waste of money. Nikon d3000 is the cheapest among the dslrs, i think i will purchase it next time.
