To Set Builders...

I agree with the majority on here. It is definitely cheaper to buy sets than to build. Shipping costs are a killer for individual cards or lots. When collecting a particular set, I almost always go that route. For me, key cards were not in the condition I typically wanted and I have always had to replace a lot of the key cards - particularly the Mantles. In addition, most sets aren't master sets (if you collect master sets) and variations aren't included. Although I don't collect master sets, it is fun collecting some of the key variations like the mid series gray back cards in '52 Topps which are extremely rare.

70, 71 and 72 high numbers can be pricey, might be best to purchase sets or at least large lots those years, maybe piece together the 73-75 sets and then just buy complete sets for the balance from a cost perspective. After 1975 things get more plentiful and full sets can be had at a fair price.

for the responses so far. My current strategy is to purchase a nice starter lot and then fill in stars/upgrades from there. It seems with this strategy you can save $ and enjoy the process. I've also joined a few trading sites so sometimes I've been able to trade away other stuff to get the numbers I need. In terms of shipping, I try to wait for a "set break" from a seller with reasonable combined shipping policies...
