Definitely pricey. I've got the regular fold-down traps...but when I say not much extra room I'm talking about wife, 3 year old, 1 year old, dog and enough crap to get us through a couple nights on board. Any of you that have kids and a high maintenance wife know how much s$%^ comes along on a two or three night adventure. I usually just toss my traps up on the bow (next to the kid's bike, stroller, lawn chairs, bbq, beer cooler etc etc), but thought if these things work it would be nice to have a trap or two that could fit under a seat or in the bilge to keep the clutter down.
Canadian Tire had them on at a decent price a couple weeks ago.
