Hi Jbakic,
I'll join the Good chorus.
If this is the first better-date Walker for the collection, you still have several to buy that will cost more in Good condition. Although the 21-S is often considered the key to the set in high grade, at this grade level the 16-S, 21-P, 21-D, and 38-D will all be more expensive. The 21-D is the priciest with a retail value in the $300 range.
