Any reviews on ReCaptcha?

Hi, I'm building a simple html website for a organization using google's Page Creator.
It's one of those "info only" webpages.

I would like to add one of those "view image" email contact forms and came across this ReCaptcha from Carnegie Mellon.

This sounds kinda of neat in that it's cleaning up scanned pages by issuing those words in your form that people visiting would be typing to contact you. Has anyone else used it or see that there might be other ways to load up one of these type of forms in a simple web page?

Thanks!

There are a number of different techniques, scripts, services, etc. that are available for CAPTCHA. This is only one of many.

At a glance, it looks promising, but there's not telling how easy it is to implement.

IMHO, I'd never go with a seperate hosted service...they can go under, change, or update without warning, leaving you in a situation that breaks your site, or puts it in a standstill.
