Thanks for the replies. The Currie scooter is 52 lbs! Probably won't work for me. Folding electric bike is too inconvenient (I need a quick fold).
By the way, the stairs are spread out across the commute, so I don't climb them all at once.
Looks like the sky is the limit with go peds- $3000 for a scooter is a bit rich for me! Even the cheapest is over $1000. The one you chose (Iped 8) would be my preference as well. It's $1399 and goes 18 mph. Looks like it meets my specs other than weight (28 lbs). Looks like you can choose econo mode (9 miles at 9 mph) or performance mode (4.5 miles at 18 mph). I can't imagine riding this sucker 9 miles, so performance would be the way to go. I'd like to try one one, but at $1399 I can't see it taking the place of my xootr.
