Sounds a bit high to me, but it could be correct, depending on your local market conditions.
Shouldn't have been any major changes in the model during that time frame. Different grips, probably.
You didn't say if it was stainless steel or blue. SS at that price might be a reasonable deal nowadays; blue, not so much, in my opinion. But that's me; you have to make the call for you, based on your preferences.
