One of the first things I did was lose the lens cap for my P2V+. Today, I stumbled across an über-cheap replacement...... the cap off a small can of propane sold at the local hardware store! A bit snug, but it's flexible enough to stretch and fit. And no, I didn't steal it... I had purchased a can last week for work and noticed the cap sitting on the dash of my van today. I thought, "Hmmm.... I wonder if this will fit my bird?"
