I pulled the trigger on the LE and have absolutely no regrets. That being said, the art on the premium is stupid good as well, so if you want to save the cash you'd still have an incredible machine.
I truly don't think you can go wrong either way on this one. The LE has the same function as the Premium, so you wouldn't be sacrificing any game play (with the exception of a shaker that I'm sure you'd add anyway). The art package on both are top notch, so that's a plus as well.
If you're even considering an LE, I would hold onto your spot. Very, very few of these going around and most distros sold out quickly. You can always downgrade later if you find it not worth the cost of admission, might not be that easy to move up though.
