Script to add to local Admin group to multiple computers

Hey all, I am looking for a script VB or powershell that I can run with Psexec to add users to the local admin group to multiple computers at once.  I get requests to add users to these computers' local admin groups so that they can test applications. Well there are over 50 lab computers, I am trying to avoid going to or connecting to each Computer Management MMC to add them to the group.

if you have all of the systems on a domain create a user group with the users you want as local administrators then make a text file 'computer.lst' with the name of all the systems then run the following command

psexec @computer.lst net localgroup administrators [domain]\[local-admin-group] /ADD

If you are not on a domain you will need two text files, one with the computers and another with the users and use a nested FOR statement to read the files to add the users.  let me know if you need this.
