Camera: *ist DS
Lens: 18-55mm kit
Lens: 50-200mm tele zoom
Flash: AF360FGZ Pentax flash
Monopod: Bogon Monopod
Memory: 3x 1GB SD Extreme II memory cards
Memory: Epson P2000 digital wallet (I plan on shooting mostly raw, so max space is necessary)

I'll post an update at the end of the vacation to tell you how everything worked out in Mexico.
