Thanks for the advice jlc1978

I might do that (next time)
Update:
Long story short. Returned the Air (256) back to original BB, decided to spend my money(so to speak) else where. Seeing from the posts on this thread the law of averages seem to indicate biggest success with the Air (128).
Different BB
SUPER nice sales-lady set the tone. Got the 13 (128). $1235 discounted further by nice Mac guy $35 put me at $1200. Haggled for $100CG with Mac guy, sales-lady backed me up by confirming the edu promo. Got a SKU from supervisor. $100 GC in hand.
$1235-$35 PLUS $100GC + tax AND 18months 0% SUCCESS!
So basically $1100 plus tax 18 months 0%
Looking back, as another poster already mentioned would I have done this again? NO. It was a slow 'news' week so I was like a dog with a bone.
Going to open my new Macbook Air (from Powerbook 17" 1.33 to a handme down black Macbook, looking forward to it.)
Back in my hole, lurking.
