Midwest equipment, espcially the mini hooks, standard hooks, animal grabbers, big hemostats and large feeding tongs. As previously mentioned (thank you Mary) we do sell these, but they can also be bought from Reptile HQ in Toronto (in Canada).
Heat guns. Currently, all I've ever used is the Raytek MT2's for food safety, the ones we used to sell. In the near future, I am going to try the ones Ravi at the Monitor Spot has for sale.
Rep-Cal, and Herptivite - the only 2 supplements we use, and have ever needed.
Bright stick compact disposable flourescent light, for the non U.V needing reptiles. The tortoises get Verilux and sunlight.
Notable mention would include Nix as preventable medicine, Black Knight for new additions and quarantine, Flexwat, Paper towel by the case, landscape bark by the pallet, human heating pads, hardware store heat lights, electric space heaters, Rubbermaids, Kitty litter pans and cheap plastic dog water dishes.
This is a good thread, I'm sure I'll remember more.
