I can vouch for the alvey. I managed to fill mine with sand after an unfortunate episode with a freak wave. The reel continued to work perfectly until I got around to giving it a proper clean. As for spinning reels, you should,be getting more than a few trips out even with a ‘cheapy’. I always tighten up the drag and use a water spray bottle after use rather than soaking the whole reel. This seems to work okay.
