Robots.txt best way for blocking urls with ? in them?

[MrBlack]

I have a site that uses a ? in the url for pagination.

e.g mywidgets.com/widget.html is the base url and all the urls for pagination of this url is are mywidgets.com/widget.html?page=2, mywidgets.com/widget.html?page=3 etc

So I am thinking to block the spiders from these paginated urls (which all share exactly the same metadata, title etc) I need to add the following line to my robots.txt:

disallow *?

What you guys think? is this the best method?

The metadata and the title are the same but is the text on the actual page the same? If the content is different I would not want to block it from the search engines. If the content is the same you may want to block it.

Using wildcards in the robots.txt is an easy way to deal with the situation but smaller bots do not support it. My personal preference would be to change the url structure of your site.
