David, as you probably know, Moro Swords is a very difficult title to find. If you have done some internet searching you have probably seen that one of the only available copies of this book can be had for the low, low price of just under $2400 USD.
Before this i had seen a few copies floating around in the $800 vicinity, but i also know that one of our own members recently sold a copy for something closer to $400.
Given this incredible range from just plain expensive to ridiculously over-priced i think it might be helpful for you to qualify your own remark with what you actually mean by "reasonable price". I suggest this because i am sure many of our members may well own this book and if they had an idea of approximately what you would be willing to pay you might possibly draw out an offer.
Best of luck!
