Personally I prefer data entry validation to Captcha. PHP has a nice little "clean" function that strips out the characters that tend to break scripts. I never allow raw visitor-entered data to be parsed as a SQL command, or as a line of PHP for that matter.

Having secure forms isn't that hard to do!

Captcha is most useful (IMO) for registration-type forms where registrants acquire some privileges on the site. I have yet to see Captcha used for quantity fields, site searches, or the like. Or even here!

I think Captcha is not needed except for a few situations.
