I focus on just one "priority" set at a time, and buy cards from that set every time I see one.

Then I have four or five "secondary" sets that I am building more gradually, and when I do not find any cards from my priority set, I "dabble" in card from the secondary sets. Dabble means I buy a card once week or so, but I am careful to leave sufficient funds on hand to buy a priority card whenever a good one becomes available.
