I haven't noticed them getting any cheaper, Larry, especially when they approach the condition of this BSA. A lot of the 700s I've seen don't look as nice as this one, either.
We have guys here who wouldn't clean the metal shavings out of a model 21 action if they thought they were original, who will tell you to alter a high condition Brit gun and who should do it for you.
The spreader load is the simplest, cheapest, and easiest solution to whatever the "problem" with this gun might be.
Really, I'd use it for at least a year before I did anything to the chokes. Maybe two years. Once you get out of the forrest, and onto the plains, that is a sweet choke combination. Not a horrible sporting clays combination, but, you will have to do your part.

Best,
Ted
