I'm assuming you are in GJ. So here is a list of places I would look. (all Links)
NRS Gear Swap
(search for raft)
Grand Junction Free Press (on side bar... classifieds ..... search ... Merchandise & Recreation .... IN .... instead of GJ Free press choose All 5 Dailies ( gets you Aspen Times, Vail Daily, Summit Daily News, Glenwood Post Independent and GJ Free Press)... Keyword ... Raft
There is a nice Maravia in the gear swap that is close in profile to a puma or super puma.
Greg at Timberline Tours 970-390-3020 has a bunch of rafts as well
I have a super puma and love it for r2 to r7. I have also used it as an overnight paddle raft with 4 people and support for 3 kayakers.
IU have a frame for it that I have heavily modified for my particular uses. Have done 7 days with 2 people on it. It is a tight fit for 4 people on an overnight as an oar rig, but it can be done. The super puma can go down anything. It is quick and stable. Great in low volume rivers and big water. I found mine here on the buzz. Screaming deal... $1650 for the rubber, a frame, 3 oars and 2 paddles. Thanks steven.
Hope this all helps.
