I've had bad luck with the less expensive Shimano reels. I had one that I paid more than $50 for, and it failed fairly early. I sent it back to Shimano and they replaced it with a newer model, a Corvalus CVL 300. That one failed as well. It's on my desk right now, with extensive corrosion bubbles beneath the finish.
On the other hand, I have a Shimano TLD 25 on my boat rod, and it has been wonderful. There have been no issues, and the reel is in fine condition.
