Cloning PCR products

I've used uracil DNA glycosylase (UDG) cloning to construct libraries
from products created by degenerate primers.  It is fairly simple and
straightforward.  You use primers modified with (CUA)n to amplify your
insert and vector then mix them in the presence of UDG.  The UDG degrades
the U in the CUA, leaving you with sticky ends.  You don't need to ligate
and you can transform this mix directly.
