Dear Bruno,
I'd recommend you look for a South Bend 290. It's a 7 1/2 foot 5 weight and you should be able to find one in very good to excellent condition with 2 tips for about $ 300.00.
Staying with South Bends you can also look for a 323, 346, or 359 in the 8 1/2 foot length. They are more common in the 9 foot length but I think you will like the 8 1/2 'er's better. You can find one of these in the $ 125.00 to $ 250.00 range depending on condition.
Lot's of people turn their noses up at South Bend's but they made some nice rods and they won't break the bank.
Staying around the $ 300.00 mark allows you to look at some other makers too. You can find Granger Victory's in the 9' foot length for that kind of dough. The 9050 is the lighter version and it throws both a 5 or a 6 weight line quite nicely. It will be substantially heavier than a 9 foot 5 weight graphite rod but it's not like you need to be Conan the Barbarian to use it.
If you want to look at Heddon's you can find 8 1/2 foot versions of many of their rods for around $ 300.00. Try to stick with models that have #2 ferrules as they were trout rods. Heddon also has 1 3/4 ferrules on their lighter trout rods but they are more money, and 2 1/2 ferrules on their bassier rods. Heddon model designations should always include the ferrule at the end of the model #. EX. Heddon Model 17 8 1/2foot 2F.
Every rod I mentioned here I own and you are welcome to try them out should you get out this way. Just holler and I'll bring some along and meet up with you.
Don't be afraid of Ebay either. I'm not telling you it's your best source but there are plenty of nice rods still out there. You just need to approach buying with a price and quality goal in mind and you'll generally do pretty well.
If you want to take some of the risk out of things then by all means visit Clark's Board that Rolf told you about because Rolf is a good friend and he'd never steer anyone the wrong way. They also sell plenty of rods there and the sellers are all good honest people who aren't out to scam anyone. It's also worth visiting just for the wealth of knowledge that the board members possess and you can learn a great deal just by reading.
Good luck dude!
Happy New Year!
