I share your frustration, I'm looking to install some sights, too -- my wife went to a ladies day at the gun club, was introduced to diopter sights and loved them.
Something our crap-avoiding members failed to mention, it may not be a simple matter of just putting iron sights on a rifle intended for a scope. The scope ready guns typically have stock combs at a height designed to accommodate scope viewing. You may, after installing iron sights, want to lower the comb for a proper fit. When selecting your gun, be sure the stock material and finish are amenable to alterations. You don't want to face messing up a new stock after you've installed the sights.
It seems your question wasn't as simple as you'd initially thought -- there are no stupid questions.
