I made one out of a plank, a lower half of a pole I broke, a piece of threaded rod, a bunch of metal fender washers, a couple of nuts, and a couple of big thick rubber washers.

First I hacked off the old pole just above the first eye. Then I glued it on to the plank with some polyurethane adhesive I got for two bucks at home depot. (Hang the end over the edge of the plank so you can still attach a reel to it. If it has a long handle you can remove it too.) I bent the threaded rod into an "L" shape, drilled a hole in the plank, secured it with a couple of nuts and washers.
Then on the threaded rod I put on a nut, fender washer, rubber washer, fender washer, spool of line, fender washer, rubber washer, fender washer, nut in that order.
Tension on the spool is controlled by tightening one of the nuts on the threaded rod.
Put a reel on the pole, attach the line and reel away to fill it.
It's cheap, ain't glamorous, but it works.
