The Jericho is a great stand in for a Stock II at half the price and the internals are almost identical. Plus the Jericho has the long hammer spring like the CZ, I run an 11.5# in mine with no light strikes, 13# in a Tanfo with the short spring is right on the edge, like the 8.5# in my Jericho. The downsides are on flared mag well, no aggressive grip checkering, no cone lock barrel and fewer sight options.
