Some quick searching makes it look like they are the manufacturer of Star Inflatables. I didn't see any real river rafts offered under the zpro label, nor did I see a clear retail outlet, but I didn't look that hard.
I'm guessing you are referring to the one for sale on craigslist in Loveland? I don't know anything about the brand, but for what it's worth that thing's been on Craigslist forever, probably at least 6 months now. Looks like they are asking $1500, which seems kind of high for a brand no one has heard of. You can get a new RMR boat for just a couple hundred more.
