ho ho... Having laid on one of the Q-Cores after a week of high enjoyment with a BA aircore of some kind, I have have had my sights on one, ever since. The weight, which I'm willing to carry if need be, has been a justification to wait, however.
Now, I see an SL version and can only thank my lucky stars that the thing isn't available quite yet. There's time, there's time... but "Does anyone know when this will go on clearance?" :)
