I haven't ridden the Contis only because the Michelin PR2 and 3s have worked so well for me.
Ebay used to have plenty of sellers selling pairs for +/- $65. PBK used to have them at a good price too.
I would stay clear of Specialized SWorks Mondos, I bought a pair and tubes would spontaneously explode on me.
LBS replaced 2 pair free of charge before I finally gave up and went back to the PR3s.
