I regularly follow M67's and M15's on GB (only option) and am here to tell you the price swing on both models is amazing. I would say from the GB standpoint that the $450 W/no box or additions with or without original grips is a very good price. Don't forget to add the associated cost if it is an auction. One thing I do see that is most promising about these 2 models is that the supply is still very good even on the M67 ND which some see as a bonus, not that I necessary agree with that as the SS sight was actually replaced after complaints due to its reflective quality. For a shooter I would just as soon have a dash 1 or better yet both a model 15 and 67 before the supply does start to shrink. I still think you can write your own ticket on these models. I was lucky to have purchased on GB a 95%+ with box and complete contents for $525 plus additional cost and was amazed to find I was the only bidder. I think in the end it just depends on what type of package you desire.
