It's a great, awesome magnum caliber. The s&w n frame handles the recoil of the 41magnum very well. The weight ratio to power is spot on. My model 58 with the 4" barrel is awesome to shoot and very controllable with the less recoil it has. Trust me you will love it.
As far as price I've seen these between $500 to $750 some even higher. Prices do vary. Look closely at the condition, check the cylinder timing, the holster wear if it has any, the finish and the bore. Remember to haggle. When going into the battle of haggling I set a limit on the price before the war starts that's my walk away point. I would look the gun over and point out any flaws. No flaws? Does the wood grain match on the grips? My point is to find something. Now start out low around $400 show him four new $100 bills fan them out. Remember to never show your bank roll. I put $10, $20, $50 & $100 bills in each pocket not to show exactly how much money I have. Play the haggling game it's fun once you know how.
