Check out B&H Photo. I bought my Steiner from them a couple of months ago and saved $250 off the list. They have used, as well. Here's a link to the scope search:http://www.bhphotovideo.com/c/search?ipp=100&sts=ma&Ns=p_PRICE_2%7c1&usedSearch=1&pn=11&N=0&Ntt=rifle+scop
Used is basically as good as new. Best advice I've seen is a used NF.
Say he chooses a scope with marginal MOA, how well do adjustable bases work? Do you think it's better to look for a scope with more MOA?
