All rafters aren't created equal, same as everything. For instance, if all I'm going to do is ride a bike around town a huffy will do, whereas if I'm going to race professionally then I'd need a specialized stumpjumper at a minimum.
The typical rafter runs class i-iii. So if said rafter is in that category why spend $10000 for a Raft package, when in reality a sevylor or a tube would work fine. If someone wants to drop serious coin for a sotar etc that's fine, but to basically require all rafters to use highend shit is stupid...its not needed.
Saturn is a specialized hardrock, rocky mountain rafts are a specialized rockhopper, and sotar/aire/maravia is a stumpjumper/epic whatever. Pick the right tool for the job. No need for $10000 Raft on the stillwater river for instance, but one would be required/recommended for the nf Payette. Same goes with remote multi day trips. Right tool for job yo. I think it's funny seeing a bunch of $10k+ rafts doing the beer run from golhill to rogue river. To each there own.
