Whatever you do get the best rod you possibly can. If you get a crappy rod you will struggle. For panfish the real wont matter much. Spend the money on a good line. If you don’t have to worry about being delicate you can stick one size heavier line on the rod and it will cast easier. I would look at used rods on eBay. You will get kore bang for your buck. Look at TFO if you want modest price and a decent rod. I got my first flu rod my senior year of high school. I was in San Antonio with no fly shops. I read orvis beginning fly fishing and taught myself. I would consider a lesson or two upfront. Will save you from breaking bad habits later. Whatever you decide, enjoy the ride!!!!!
I am in the other camp when it comes to fly fishing gear. I have been flyfishing for about forty years now and have owned really nice rods and inexpensive ones. I once owned a very nice Orvis 9wt. Had the latest and greatest rod blank, fancy guides, reel seat, etc. Well, one day the rod tip broke and I had to send it in for warranty. It was going to take a few weeks and I was going on a trip in a few days. So I picked up an inexpensive cortland rod for like 30 bucks (mind you this was over 20 years ago). I was blown away by the rod. It was actually better than my $450 dollar Orvis. It was all about the action. The cortland had a faster action, allowing me to really load up the rod and snap the line through the wind. I sold the Orvis.
I also own a 30 year old sage 2 piece 5wt and a new piscifun 4 or 5 piece 5 wt. The sage is really nice but just too soft of a rod, except for those windless days when I need to drop a dry fly softly. The 30 dollar pisicifun blows the thing away every other day a thousand times.
The low end market has a lot of value. I think rods under $100 dollars are very good and the higher up the price range you go in this category, the better the components. The next level, up to $300 or so, you are probably getting into better blanks, but I would bet in a blind test, most people would not tell the difference. After that, it just gets to a point of diminishing returns.
Same goes for reels. Man, can you get your hands on some decent stuff for not a lot of money. For panfish, and most trout, you are not relying on drag very much. But I have to admit that the drags on most of these reels that are around $50 are very good. If you fish saltwater (that was what my 9wt was for) or are getting into salmon and other species that can really make a run, a good drag system is needed.
I do not worry about warranties anymore because I can buy ten rods for the price of a higher end one and still have one hell of a rod. Same goes for reels. One other thought about rods. I cannot imagine that there are numerous rod blank manufacturers around the world. I bet they come from a few different factories, just rebranded.
As for lines..... I have yet to figure that one out other than if it has no memory, it is good for me. I just tried out one of the cheap ones that comes in a ziploc bag instead of a fancy box. It was for the 5wt. Works as good as my more expensive stuff. Go figure.
Your options in fly fishing are dizzying. Don't blow your brains out on the gear. Just go out and have some fun. They all catch fish.
