With this pilot market, you should go ahead and get it. If you find that you need it later, it's already in your wallet. If you don't have it, you will probably miss the window on any CFI job that is offered you.
You should also reconsider instructing. I wasn't too thrilled about it either when I was out to get my first job. It later became an experience that I wouldn't trade for anything. It was very rewarding.
Hopefully the Lindbergh estate will not mind my copying a paragraph from :The Spirit of St. Louis:
"I soon discovered that I was learning as much about flying as my students. A pilot doesn't understand the real limitations of his aircraft until he's instructed in it. Try as he may, he can never duplicate intentionally the plights that a student gets him into by accident. When you're flying yourself, you know in advance whether you're going to pull the stick back, push it forward, or cut the throttle. You think of a maneuver before you attempt it. But you're never sure what a student is going to do. He's likely to haul the nose up and cut the gun at the very moment when more speed is needed. If you check his errors too quickly, he loses confidence in his ability to fly. If you let them go too long, he'll crash you. You must learn the exact limits of your plane, and always keep him far enough within them so the wrong movement of a control will still leave you with the situation well in hand. You must learn not how high the tail should go in take-off, but how high it can go without disaster; not how to avoid a wind drift when you're landing, but how much drift there can be when the wheels touch, without a ground loop or blown tire resulting. And after you've learned how to keep a student out of trouble, you find that you've become a better pilot yourself. As you instruct your student in the primary art of flying, he instructs you in its advanced phases. In a gust of wind, or if the engine fails, or in any emergency, you handle your plane more skillfully than you ever did before."
I don't think there are many former or current instructors here that would disagree with Mr. Lindbergh on this one.
Whatever you decide, best of luck.
