I bought an Orvis Battenkill many moons ago, and I have just stuck with them. They meet all the criteria Fishinwretch set out, though I can't tell if the knob is gay or not. They're metal, have a....
This just in: I just checked (figured I'd give you a link) and it appears they have discontinued the old-time Battenkills I was going to recommend. I do have one of their Access reels (which used to be called a Battenkill something or other) and like it very well. But it's fairly new and doesn't have a lot of turns on it.
Some other things to think about:
Size -- be sure to get one sized for a 5-weight line, which can include 4, 5 or 6. Obvious I know, but figgered I'd mention it anyway.
Material -- I'd go with a metal, preferably adonized not painted. Less likely to get dinged up.
Drag -- it's really not of major importance, but do make sure it's adjustable and of sturdy build. Disc drag or click and pawl both get the job done. The clicks don't bother me like they do some. When I'm in a big fight, I'm usually palming the reel anyway.
Backing -- get the backing on there to the proper depth. Not for the huge 200 yard runs you'll encounter, but to get the build up beneath the line so that together they just fill the spool. That'll make for fewer and smoother cranks when you're reeling in.
