uTron is a genuine Topre split keyboard and ludicrously expensive. 500+ washingtons for it. For that cost you can buy two Topre keyboards and they're expensive enough!
Worst part is that the uTron is seems rare too, one listing of I've seen on eBay and that sold for 600 USD. Looks like it's nonexistant on Amazon too.
I won't go hoping for a split Topre board anytime soon, the best you can do is just sit and wait.
