+1 on the Dragonfly if you're trying to reach a certain price point. As far as weight....I would say if you want the "all around" rod for being able to take to a lake or a river, I would stick with a #5. If you get into a larger trout, you're going to have the backbone needed to land it faster. As well, you can use it to troll a fly, chironomid, use indicators, some split shot, and not have to worry too much about it. The Dragonfly would work great for you, because you can buy them as a combo package. They come with the rod, the reel, and a spare spool. All lined with a full floating line, and a sinking line. Which is excellent to get you started. I started with the Dragonfly combo, which has now led me to thousands spent, but thousands of awesome memories on the water. My Dragonfly was a #6 which I still lend to a friend when we're out to try and get their addiction fired up as well.
But yes, totally agree on the buying local. The whole rig will be rather inexpensive, and anybody at a local tackle shop will be able to help you in the right direction! Happy hunting!
