Would you buy a refurbished pump?

I took my single speed 1.5hp Pentair Superflo to a pump shop to see if it can be repaired. Quoted $250 to change bearings and some other things. They had a Hayward TriStar VS 800 that they had just received for warranty replacement. He said it was just a few seals that needed replacement, he would sell it for $650 cash w/6 month warranty. ($2000+ pump brand new). Is it worth it for the savings, or am I asking for trouble?
