The cost I'd be wary of is 5 battlechests for 20$, wolk 5x29.99 (if stays the same price) cata 5x50. 500 is a hefty price, but if your not totally itching just yet (which I doubt, probably day dream about It like indid when I "quit") but consider waiting till they maybe release a wow,bc,wotlk battle chest. But ...I haven't heard if that will exists or not.
