Free Tool For Twitter DM?

I know some paid tools, and the paid subscription of socialoomph allow this....
but is there a free tool to send a DM to all of a twitter account's followers??

even if there is a paid program that does this that allows a trial period (without requiring credit card) I'd try it out just to see if the conversion for what I want to do would be worth it.....

THANKS

I would like to know too.
