Manual Fan Switch Location

I've been wanting to do a manual switch for a while but just haven't gotten around do it. Found this "how-to" http://www.corral.net/plugins/p2_news/printarticle.php?p2_articleid=9, anyone use this method before?
Well now is a good a time as any to go for it but was looking for input on where others have located the switch. I have a Vert so I don't have the coin holder area open, was thinking of maybe using the painless panel that goes in the ashtray. Anyone have experience with these swtich panels?

The push button start seems kind of trick, hopefully you could still use the conventional way of starting the car but have the option of showing off with the push button. Would push button seem too ricey?
