Look at Cabelas
Cabelas has a Redington RedStart II with reel, line and backing for $199. Cabelas says they are for saltwater as well as fresh. These carry a great warranty from Cabelas.
Re saltwater corrosion, most rods and reels will last more than 1 year if you treat them right. As soon as you get back to your abode, take a shower with them and wash them thoroughly
