FMS is ok, Gi Joes has some as well. Don't know clacka prices, but most places they are around 150-170 each oar. There are a few online places as well. Try NRS.COM. You'll have to go to the oar and paddle page, that will give you an idea of what to shop for and comparative prices. Good luck.
What size you looking for?I may have a set of 9' cataracts for sale. I also have a set of Sawyer lights I don't use.Not sure on that length tho.....
