I've landed Chinook to 43 lbs on an old Dragonfly Expedition 8wt fly rod. The rod handled it quite well actually and it caught tons of smaller ones, coho, chum, sockeye and pink as well. Was a great rod for the money and lasted around 10yrs before I sold the setup to get something else.
I don't buy super expensive gear for salmon because it's going to get thrashed on anyhow and I don't want to cry if I break the rod. Cheaper stuff that's still very decent is what you should look for.
The current setup I'm using now is
Rod - Orvis Clearwater 8wt 10' (8100) - $259.99
Reel - Okuma SLV largest size - $99.99
Line - Rio Outbound Short 8wt - $99.99
Only thing I might replace is the reel but I'll probably use this one until it dies
Good rod to look into is the Echo Base which retails at Wholesale for $100 and was the rod I almost bought however I prefer the 10' rods
Have fun shopping !
