Curtis, welcome back to the fold! 
I'm curious as to why a 9-ft, 6-wt? Reason I ask is that a lot of fishing around S'port, including the trout tailwaters at Mt. Fork and Little Missouri, is done with a 8 or 8 1/2 ft, 5-wt. So you might have better luck finding a used - or as you requested "seldom used" - outfit of that length/weight.
Also, Bass Pro in Bossier City currently has SciAngler fly rods for sale for $19.99. They're all 5-weight models in stock, and are 9-foot long. I've not had a chance to check them in person at either store, Bossier or Denham, yet. But if they're anything like an SA rod I owned for a short while, it's a very decent beginners rod. Also check out the Temple Fork Signature IM6 graphite rods. They're $99 but they cast very well for the money and come in all lengths and weights and have a breakage warranty. Go to www.templeforkflyrods.com and check them out. Either option, you'll have much more fun casting it than that fiberglass.
I do have an Okuma rod I'd give you except it sucks. I use it in presentations as an example of what NOT to buy! Won it in a CCA raffle... it came with a reel and I was trying to win the reel. The rod has 5 guides for a 9-foot length. Golden Rule is 1 guide per foot of rod length (ideally, 1 guide per foot + 1 extra). The line sags so much between the guides that birds can fly thru the hanging loops! Just beware that a decent fly rod will have good guides, the right number of guides, a cork grip, and not be very tip heavy. Unless you're fishing saltwater, the reel just needs to hold line. Just about any reel will do, but avoid automatic reels!
Good luck with your quest!
