Sadly, I think it's questionable using anything from a place called "Surplus Center". At least as the rules were last year. If they don't have enough stock on hand to service a good percentage of FIRST teams, they don't count as a COTS supplier. Looking through the inventory, I don't think you could defend something if they only have 61 in stock. Unless you can find it actually for sale in single units from somewhere else, in which case I'd think you'd cost it at that retail price but actually purchase it from the surplus center. So the sprockets would be fine since those come from McMaster, MSC, etc. But I'd be rather wary of most of those gear boxes.
