Before you tell me "this isn't P3 specific" , it is. I only own and have tested with a P3 so not sure how it may impact others. If mods want to move this...be my guest. Anyways, Costco, 20$, it's a kids arts and crafts table by Lifetime Products. Does have a metal frame and legs but they appear to be insulated enough it does not affect calibration. Compact enough you could leave it in your backseat or trunk "just in case" the spot your flying from has uncertainty. It is not something I'd want to carry around all day but isn't bad for what it is. It's actually pretty sturdy, I'd assume it would hold a few kids standing on it. Also makes for a great stand for a hard case (I have an HPRC, perfect size) when not flying. If your wife clamps down on the cost just tell her you want a table for the shorter members of the family for the next BBQ. Just stop her before she buys the chairs.
