Of course, the only reason I would go for the Enya Nova is the price difference and the included goodies.20% off is a good price for a good uke. I recommend you jump on it so that you get it sooner and can start enjoying it. A "bit out of my budget" becomes unimportant once you have it in hand.
I would get an aNueNue over an Enya (I had one and gave it away).
