My two completed sets are T205 base set, (many towards the master set, too) and 1927 York Caramels. The gold borders took about 13 years and the Yorks maybe 6 years (60 card set).
I have 24/25 from E95 and will finish that one in spring 2012 if my plans work out.
I have actually stopped doing any new sets. I still have E96 and C46 underway but recently gave up hope on E90-1, Fan Craze, Diamond Stars and Batter-ups after decent starts.
Commons,short-prints and high numbers have steered me away I guess.
I am focusing back to HOFers, where my heart really lies.
Good idea for a thread, its been awhile since we talked about full sets (other than t206)...I think
