The wife and I have had a pair of Shimano Symetre 2500's that are going on 3 years with ZERO problems.
Trust me...they've been fished HARD, tackling large reds, jacks, spanish and black drum from a kayak in Louisiana and Texas.
The only thing I've ever done was hose them off when I got home, shook off the excess water, and then sprayed them down with Reel Magic...oh yes, each year, they get a new loadup of Power Pro 8 diameter/30 lb test line.
I am about to make my first 'break' from the Symetre and go with a new Stradic 3000 on my custom Billy Stix rod that my superextraordinaryincrediblyhotsuperwife got me for Christmas.
One more thing...I don't think you'll be disappointed with any of the reels from Shimano. I have a Slade 4000 on a Shimano Sojourn 7' spinning rod with 50 lb power pro on it. I've abused it, used it, beat on it, and I can't kill the thing. I have less than $80 in the setup, including the line, and it's still smooth, the drag works great, and it's probably been the setup that's responsible for the most reds put on my grill.
I don't work for Shimano, I don't get paid by Shimano...I just fish a LOT, and I love their products. I have NEVER had one fail me...I cannot say the same for other brands.
