"Pretty good" isn't precise enough to determine the quality of the finish.
The grips are a detraction from value. It will cost $50-$75 to buy the correct ones used.
Which model? A model 29 is worth more than a 29-2 which is worth more than a 29-3 etc. Again, you must be precise in description.
Box and tools included?
The long barrel is least popular and values lag behind the shorter models.
A 29-2 in 95% without the box and with rubber grips would likely sell for around $450-$500. If in the box with the correct stocks then $550-$600 or maybe a tad more.
These are my estimates, others will say otherwise.
