My lineup is pretty much set in stone now, so I keep up my interest in the hobby by upgrades and add-ons (like a 3-D translite for AFM and a ColorDMD for TZ added this year). But my most expensive accessory is the 2013 Mustang Boss 302 I just bought Saturday, to go along with my Stern Mustang Boss premium pin. I run a slide show of my cars (off a thumb drive) on a wall-mounted 23"TV next to the game and I'll be adding several pics of the gotta-have-it green Boss 302 to the slide show (hence the car is an accessory for the pin).

(Sorry about the generic photos, but I haven't photographed my own Boss 302 yet.)
