What script callback to use for the site?

Thinking about the integration of the site script, which will catch the users and inviting them to request a call back. As the script you use and what do you recommend?

Considering a few solutions:
1. Integration Callbackhunter, hookmyvisit or Livetext
2. The integration of a simple form callback( question what. While the chat)
3. To buy an existing solution and adapt it( what a question)

Please share your experience.

A normal button next to the number in a prominent place. Other whistles (like Callbackhunter) just enrage already.
