Hi, I've heard that a lot of captchas (including google's) can be broken by spambots. Do you know a good one, that can't be broken?

Text captch (http://textcaptcha.com/) is a good alternative and indeed accessible.

I am using http://www.123contactform.com for my web forms and I was curios how safe their captcha is. They also use some kind of text captcha.
