Lens resolution test chart suggestions?

We toss about the concept of lens sharpness all the time.

We rarely get consistent and objective in our assessments.

Facts and data can quickly destroy a perfectly good emotional rant but the empiricist scientist in me is longing for something reproducible and objective.

Before someone says "You might be a photo-geek if..."yes I already know it. My kids tell me.

Does anyone have an easily available, affordable, anyone-can-own-one suggestion for a resolution target chart.

The web search turns up the Edmond Optical charts.
Suggestions anyone????

Some are reasonable, some not.

 

Found another....

My old reliable HP 4P does a pretty respectable job, better than I would have thought.
