How to Open a copy of the current Finder window via AppleScript

Sometimes I find myself needing to open a second copy of the current Finder window I have open. There's no default way to do this in Mac OS X, so I wrote a small script to take care of it for me:

tell application "Finder"
set this_folder to (the target of the front window) as alias
set {x1, y1} to position of front window
make new Finder window to this_folder
set position of front window to {(x1 + 50), (y1 + 150)} --This offsets the new window more than the average Finder tiling does
end tell
end try
use Butler to assign this a hot key, which then opens these copies when I need them
