If you need a resonably priced fly fishing reel for chasing Tarpon, Snook, and Bonefish, you should concentrate on a few manufacturers and brands.
Have a look at our saltwater fly fishing reels auctions page for a first overview.
Always remember that you get what you pay for, just don`t go wild untill you know it`s the reel that you want to buy.
You also can go and visit a couple of fishing shops and see which reel feels good in your hands because not all of them will feel the same.
Okuma makes some decent reels for saltwater fishing as well.
I would get an 9wt or a 10wt for the beginning.
I would not try to target tarpon with anything less than a 10wt rod and reel with a good line and lots of backing.
Based on your budget you can get a decent reel for 9 wt or 10wt from 100.00$ upwards.
