Sump pump float switch siezed - replace the pump?

[Maxforwardspeed]

My Zoeller M53 has been working great for 15 years, and my water level alarm was going off this morning. The float wasn't able to pull the switch up to activate the pump. Looks like I can get a new switch for about$100 or replace the entire pump for about $200. I'm sure the brine discharge from my water softener isn't helping. Replace the whole pump?
