If you like the zuma looks, I'd suggest a new zuma clone.
I don't know what you're aiming for, 50cc or 150cc.
50cc, <$1030 delivered:

150cc, <$1200 delivered:

For $1100 a nice 2 stroke 50cc scoot:

But if you're going regular 4 stroke, 50cc, I would suggest the smallest, and the cheapest; probably the most reliable and cheapest chinese 50cc on the market today; $730 delivered:

And of course, nothing beats this Roketa motorcycle (if you like shifting gears). Just do a sprocket change to 34T, and you'll get 95MPG out of this wonderful machine:

I just wished they had them in pink and red, for girls. I'm fond of my blue one.
