If you are looking for a true Long Cast Spool, Daiwa cannot be beat. They put the most effort into the design of their spools. If you are using braid, you can try a Daiwa SS2600 Whisker (price btwn. $85-100) or if you use braid or mono, there is the Daiwa Team Advantage 4500S which is a good casting reel (price btwn $100-140).
Don't discount the Shimano Spheros 6000($100) which casts great and has a waterproof drag.
I have two Okuma Coronado Bait-runner style reels which I use for fresh water(Carp) but they are built for saltwater use. They baitrunner feature comes in handy so my rods dont get flung in the water from a sudden strike. Its happened to me already! I really like the Shimano Baitrunner and the Thunnus but I was looking for a more economical reel for my specific use and I went with the Okuma. So far, so good. :)
