?50 reels for float work

I am considering the purchase of a new reel in the ?50 bracket for float and light feeder work. I have a Nexave3000MR which has been a cracking little reel, but I feel that it is starting to show signs of wear after fighting some largish carp and tench over the summer.
I thought maybe a new Shimano exage 4000FA would be a decent upgrade.
Has anybody got any other suggestions for similar reels in this price range?

If you're looking at Shimanos for float work go for the 2500 size.

Yes of course, however it strikes me as a curious size, most reels being classified as 10, 30, 40 etc
