The outro to Cival War by GnR is some pretty cool wah action and easy too. Also try the "Mirv Wah Funk" lesson on this site by Jon Broderick. Pretty cool sounding wah riff. I have a Les Paul classic that I ordered from American Musical Supply at a cost of around 1,899 american dollars. They have a payment option where they let ya pay 1/5 of the price for 5 months...around $389 american dollars a month.
