I don't know as I'd go so far as to install it just because its there, but I will certainly keep my ears tuned for suitable comments when it does hit the streets. We both know that there is a certain amount of iron to do the work, and that one thing done exceedingly well, will be balanced by some other aspect thats so bad the local stray cat population surplus will be quickly solved. :) Thanks Brett.
