I want to buy a new bass?

So I've been playing the bass guitar for over a year now, and my skills have improved tenfold since I started(well, at least that's what my teacher says and I suppose I agree with him.) The bass I have is a good Ibanez beginner's model, but unfortunately I am going to be honest and say that I'm getting tired of it. It's not all that fun to play as it was, and I have recently tried out a Spector bass at a shop which totally blew me away! It played so smoothly and easily, I didn't want to put it down. I had never played a bass like it. However, it is quite expensive so I want to save up for it...or should I wait for a while longer and not buy such a high-end instrument?
