There are a ton of good spinning reels out there and of course, Shimano is probably one of the best. I have tried all makes and models and found it somewhat amazing that my best spinning reel is one of the BassPro Extremes which is an 8-bearing unit and cost me all of 15 bucks. They sold them in both front and rear drag models and smooth as silk. Very well balanced and if you spinned the handle as fast as you could, there was no wobble or out-of-balance problems. Also had two sizes - a medium and large. I originally purchased two to check them out and was so impressed, I went back and got four more as backups and for spare parts if/when they wear out.
I got these reels in the Outlet instead of the main store. They originally sold them for something like 30 bucks but were getting rid of the inventory and sold them for half price in the Outlet Store. So what I am getting at is check out the Outlet Store before you go crazy in the Main Store. I believe the stuff in the Outlet Store carries the same warranty as the Main Store so you can always take it back if you don't like it.
Hate to say it but most complaints about spinning reel tangles and such are more operator problem than reel problem. If you are turning the handle on the reel when a fish is taking out line, it will twist the line something awful. Using any kind of reel without a barrel swivel with spinners will twist your line. If you get slack in the line when you are casting, it will throw out a birdnest or knot up your line if you are using braid. But I will admit that some reels are better than others and that some lines are better than others. What you want to look for in the reel is smooth reeling, immediate anti-reverse, very smooth drag and easy drag control. I think the rear-drags are the best.
Anyway, good luck on your purchase.
Cheers.....
