What price I should ask for these or are they free ??

Hi friends,
I don't have much idea about whether these forum scripts are available for free.
If it is free then its ok, If not then can anyone tell me(guide me) how much price I should ask for these. Review here ---

1. http://www.webfreakz.co.nr/ ----- phpbb

2. http://fun.full2masti.com/ ----- smf

3. http://cybersiva.com ------ ipb

Thank You.

 

phpbb and smf are for free .. and ipb is 150$+
and sell ipb only if u have got a license

 

license .. I don't know about that. Can you please help me more about that and how to get the license ??

 

The templates are looking very good.. well PHPBB is free ..
but u can get somthing for the template design and the forum setup.its upto u.

ya IPB is above $100 i guess.. the template is looking very nice..

 

vbulletin is very nice, has lots of nice add ons and mods. but sometimes people like forums because they are different, 4chan.org anyone>

 

I am using SMF and it is both free and very nice. It is easy to install (It is automatically installed from my hosting - Godaddy). Unfortunately, the smf website is down for maintenance now.
