Didn't take long for the first response, eh?
mcphats - I don't know what your experience with rafts is, but I'll assume you're looking for something to get into the pastime with and don't know much about rafts. Bear in mind you'll get a lot of answers here from folks that run Class III - IV+ water and who demand a lot of their boats.
Like a lot of things, it depends on what you want to do with it. If you're strapped for money and all you want is to get the family or fishing buds out some Class II splishy splashy water, a Saturn's probably adequate for the job.
I don't know about recent models but the earlier versions were really sketchy. Folks took them out on some real whitewater where they performed above the "pool toy" category. I've seen them run Brown's Canyon on the Ark and there are some folks on the Buzz that have been running them for a few years.
Saturn's made improvements over the years and the reputation is probably worse than the actual boats are nowadays, but that ain't saying much. I've had a raft repair man who had worked on a few tell me that once they start to rip, they just keep on going due to the flimsy material they're made with.
If you're looking for something that's one step up from vinyl pool toys (Sevylor, Fish Hunter, etc.) then a Saturn may work for you. If you want one less major thing to worry about when you launch on a rocky Class IV wilderness multiday, keep saving your money and look for a used raft made by a company listed here
or any number of other of the established quality manufacturers.
Good luck finding what you need,
