site summital Software

Hello all,
  I have been looking into many of the site summital programs on the net
and have found one to be of my likeing,
Called, 
  Softspider, Virtual-stampede, and a host of other names.  It seems that
this program is a reseller program so that is why it appears under many
different names.
  I discovered it was created by Intermost
http://www.aol.com/linklang/
and have sent email to them.  Has anyone dealt with this program before?  I
am a bit wary at the moment since Intermost didn't have any company info
page, also their credit card form seems to be insecure.
  Does anyone suggest a program?  I am looking for one that doesn't limit
the ammount of summitions so that I can begin offering a free service on my
web site.
thoughts?

Sincerely
