Is this the same SG for which you were asking about slugs? Did you hurt yourself? What happened?
Regarding value....
I shopped around for a long while before I bought my first 870. I seldom saw them for more than 300 or less than 200, no matter if they were Express, Wingmasters or HD's. There were a few guys trying to sell them for prices way above that but they rarely sold and I can only imagine what knucklehead they talked into buying it.
The problem (if you're a seller) is that they are so easy to customize that accessories are of almost no value.
I find that wood does little for the value since I can refinish just about any stock that is not complete junk. Barrels, cheap.
About the only thing that is worth paying extra for, in my opinion, is a real nice blue finish like you might find on a nice old Wingmaster.
It is easy to get even the crappy Express models to work smoothly.
As far as trade-in, I assume it would be less than resale, right?
YMMV, and probably will,
Mike
PS. My second 870 was in the "under 200" category. Live and learn I guess.
