After all my mystery box fun with the 76-77 OPC stuff, I was down to just 10 cards that I didn't have and a few I wanted to upgrade at some point. However, my focus is to get the 10 I need, and then upgrade later in life...or save that for my son to do someday.
Anyway, my LCS have many of the ones I need for this set and I have just been picking away at the slowly and working out deals when I can. I did manage over the last few weeks to nail 3 more off the list. Denis Potvin, Larry Robinson and Bobby Clarke. None of those three book for more than 6 bucks so getting those three for 10 bucks was a pretty good deal. They are all near-mint condition which means they won't need to be upgraded and that leaves just 7 more to go.
However, of the remaining 7, there is an Orr and Dryden in that mix which will drive up my final set price, but I still imagine I will be ahead of the game when it is all done. My LCS does have an Orr as well as the Lafleur I need, but I will let them collect some more dust before I go in and beat them up on a price.... :)
