That revolver in 5" is a dandy and should be fine with low use.

You always want to check the bore, and the cylinder yoke function (swings out, locks up tight, ejector rod not bent), wiggle cylinder when locked up should also be tight, obvious scratches, and the sights haven't been whacked. A bit of a turn line is to be expected (not much on stainless).
That straight up patridge front sight is better than a ramp for sighting, but can make holsters an issue (you don't want to be dragging the sight on the holster all the time).
That said, never forget to ask a seller if he has a holster and is throwing it in. If you want a holster, make sure it is designed for that front sight.
The $700 looks pretty fair to me. Here's what new ones are going for (and CA is probably always higher than nationwide averages).

I'd have to get some VZ G10 grips for it.
The Smith Pro series guns are supposedly about halfway between regular production and Performance Center. (actually, today, they're all just production) (and lifetime warranty)
