That Kuota is likely to be available for quite a while if it's overpriced, especially since very little in the world of bikes goes out of fashion as quickly as TT bike technology. Those bikes lose value as fast as older mountain bikes, if not faster.
Since you'll be flying back there soon, maybe start searching your home town Craigslist for TT bikes in your size. There's a woman who has listed a surprising number of smaller road and TT bikes for sale on Baltimore's Craigslist over the last couple of years, for instance. You can look at older Craigslist posts, too, for bikes that were listed a month or two ago that haven't sold.
If you find a bike, you should check with airlines to see which will let you bring a bike back for cheap. If they're too expensive, you can always ship via Greyhound---very cheap, and I imagine that Greyhound has service to Las Vegas.
