I like iron sights on my rifles too. I like New England Custom Gun's (NECG) "Masterpiece" line of sights. They aren't cheap, but quality rarely is. I like their banded front sight for strength and the way it looks. CZ might also make a set of irons that fits if money is an issue. I install my own but if I was going to have it done, Grizzly custom guns up in Montana knows their way around installing iron sights (http://www.grizzlycustom.com/).
