You could also try the People GT 300i, which is a little larger than the Downtown 300i, and has the same engine. The price is, I think about the same as the Downtown as well.
Of course, as you've discovered, the 300i models are new models, and are going to cost about $2k more than the 250's, because the 250's are leftovers.
Also, if you want more of a "standard" larger scooter, than a maxi like the xciting, then look for a leftover People S 250, you should be able to find one for the same price as the Xciting.
Of course, if the Xciting Xcites you, then, definitely buy it. And, as you said, it complements the Reflex well.
BTW, great deal on the Reflex (as I'm sure you know). I don't even need another scooter, and if I found that deal, I'd have to buy it.
