WTB: Waste collector for skimmer

[Stones]

Like the title says, I'm looking for an auto-shut off waste collector for my protein skimmer. I'm going to be working away from home for a week at a time this summer and I want to pick one up to avoid any skimmer related floods. If anyone has one kicking around that they aren't using just shoot me a PM. If not, could anyone suggest a retailer that carries these for a decent price? The only place I've found so far is Premium Aquatics but shipping to Canada from them is very expensive. Thanks
