I've only had one Apple laptop, I'm still using it (09 13" MBP) and AppleCare came in handy for me because a few months before the warranty ran out, OS X notified me that the battery needed replacing. Don't underestimate how unreliable battery technology is. Apple's batteries are the best I've seen, but even the best fail at some point (like mine did.)
Try to get an educational or local/state/fed gov't discount, AppleCare is probably the best discount they offer under those programs. Also, I would recommend NOT buying from eBay, because the risk of fraud (due to sellers using programs to generate codes, probably) is too great. There are numerous other threads on this topic.
