I'm not chasing many inserts set anymore, but I was always partial to some of Topps' reprint sets, such as the Trading Card History from 2008 Topps, where the Clemens card hails from. Topps would again do a big reprint set in 2010 with their popular Cards Your Mother Threw Out. Paul helped me get a little closer to finishing the set with 5 more cards. Another reprint set, 60 Years of Topps was included in the 2011 set. This Dave Winfield nearly completes that set.
I also got 3 more commons for my 2013 Gypsy Queen set and 2 inserts from 2012 Gypsy Queen. I'm still a long ways off from finishing both of those GQ sets, but I appreciate any help I can get.
